Bug Description

Binary package hint: thunderbird

Steps to reproduce:
1) Wait for a few messages to arrive in Inbox, thus being marked as unread.
2) Mark all of them as read, then archive them.
3) Click on All Mail folder.

Actual Results:
Only one of recently archived messages is marked as read (usually the newest one), the rest must be marked as read again.

Expected Results:
All of recently marked as read in Inbox and archived mails should be marked as read in All Mail folder, too.

Some updates:

1 - This also occurs in safe mode.
2 - It's not an issue of the count, but that the messages subjects already read in Inbox and not marked unread in Gmail->All Mail are showing up in the new mail notifier.

So, as follows:

I get 3 messages. I read all three.
I get 1 new message. Popup notifier says 'You have 1 new message' but the subject preview below that lists the subjects for the 1 new message in the inbox and the subjects for all the messages previously read but still marked as unread in Gmail->All Mail.

I'm really not sure which bug I'm talking about (i.e Bug 502370 or Bug 518581), but I have noticed a few things here:

0. (Yes, zero) It seems to me that TB doesn't expect mails to be marked as unread on the server when it hasn't done marked it itself. Put simply, TB is coded to believe that only it is capable of marking a mail read or unread while it is running. This is expected behavior and this is not where we want to fix this bug. (Unless you want TB to check the message ID, which may or may not be a nice thing to do. But read on, I think this issue can be fixed in a different way)

1. This can happen backwards as well. I can read the mail in All Mail and then check the mail in the other 'Labels' that mails is in and the mail will not be marked as read in these other Folders/Labels. If the initial problem is understood, this should be as well, because one of the reasons (I'm coming to the other) this problem exists is that TB doesn't recognize the Label system, and tries to apply the folder system to GMail. By this logic, the reverse issue should affect us in theory, and it does.

2. This bug is not 100% reproducible. If I read (say) 10 unread mails in my Inbox, reading the first 7 for a long time and quickly glancing over the last three, just to make them read, and immediately go to All Mail, TB checks for new mails and marks ONLY the last three as read, leaving the first seven that I took a long time to read as unread. When I have a mail in three Labels, and I read it in one, it is often marked as read in one of the other two folders while unread in the last one.

Here's my guess, for why TB behaves that way:
It does seem that when a 'folder' is not opened for a long time, the type of checking that TB does (in the background) is different from the type of checking that TB does when I open a folder (in the foreground). If a "background"/automatic check is done on the server, TB seems to check for new messages only. It doesn't check for any other changes. When it does a full check, only the changes since the last "check" seem to be recognized.

How this can be verified (over the next couple of days, I shall try these tests and post the results here):

  a. Disable all automatic and periodic checks ("Check this folder for new messages" in the folder preferences) on one folder. Read a lot of mails that are in that folder from "All Mail" and wait at least ten to fifteen minutes. Now open that folder. If this theory is correct, TB will correctly mark all read messages in that folder as read.

  b. Enable automatic checking of a folder and change settings to check every minute. If this theory is correct, this bug will be far more reproducible and should happen for almost every message. At the moment, this is reproducible but doesn't happen for all mails.

To summarize point No. 2, TB, I think, checks the server only for new mails when it does an automatic check, but when it does a proper check (when you open that folder) it looks only for changes after the last automatic check.

3. The list of read/unread messages syncs itself properly if I restart TB. Since this is the first time I'm checking in that session, I presume TB does a more thoro...

I could see similar phenomenon with Tb 3.0.3, with Gmail IMAP, using single IMAP client(Tb), during test for Bug 450246(tag case) and bug 544439(\Seen flag case).

1. A mail has Gmail Label of [Gmail]/All Mail, Inbox, X/A1, X/A2, X/A3, ...
   "Read status" at all folder
2. Change mail in X/A1 to Unread
   => mail in some folders was changed to Unread. (not opened yet?)
   => mail in Inbox was not changed to Unread.
   => mail in other foldrs was not changed to Unread. (already opened?)
"Work Offline, go back to Work Online, Click the folder" was required to reflect status change.
So, it looked for me next phenomenon.
  If IMAP folder is already opened, re-synchronization of flag is not executed.

Does Gmail IMAP return new status("no \Seen flag" status or "\Seen flag" status) after status change by other for the mail?
Does Tb know "change from with \Seen flag to without \Seen flag or vice versa" of the mail in Gmail IMAP folder?
Or Tb knows it but status of MsgDB/thread pane is not refreshed?

> and immediately go to All Mail, TB checks for new mails and marks ONLY the last three as read,

Tb knows highest UID(N) which is used and next UID(N+1) for new mail. Upon new mail check, Tb probably issues "uid (N+1):* flags". If no new mail with UID grater than N, Gmail returns flag status for uid=N. If new mails for Tb exist, Tb can obtain flag status for UID from (N+1) to (N+x). I guess you are looking phenomenon at this stage.
For old mail(UID M, M is less than N), flag status change(\Seen<->No \Seen) can't be obtained unless "uid M fetch flags ..." is issue again. I guess "status of old mail is not changed" is problem around this(phenomenon I saw).

As Gmail IMAP returns flag data of highest UID=11667 when no new mail, Tb can know flag change of highest UID(=11667 in this case) by the fetch command. So, if last mail(highest UID), this bug's problem(\Seen flag) and Bug 450246 comment #15(tag case) doesn't occur.

Or, "MsgDB is not closed" is cause? (If closed and re-opened upon click, re-synchronization of all mails is executed by open.)

Hi,
I tried running:

  $ NSPR_LOG_MODULES=imap:5 thunderbird

But there was way too much text being bombarded at me to be able to understand anything. Can you explain, since I haven't done this before, what exactly I'm looking for?

Also, I've noticed that the behavior is a lot more random than I thought it was. I have not been able to successfully "corner" Thunderbird and predict that if I do, XYZ, TB will do this. In my initial comment (#3), what I said sounded like the bug was predictable. It's not so.

Do you enable "Check for new messages upon sartup/every NN minutes"? If so, it may be by fix of bug 540214, because bug 540214 is landed on Tb 3.0.2 and MsgDB is properly closed after STAT by the fix.
If closed and re-opened(or Work Offine, back to Work Online, click the folder), fetch uid 1:* flags is probably issued and flag changes of old mails are obtained.

anything.

Get log with small folders, please.
(1) Create folder X/A1, X/A2, X/A3, Show "Order Received" column(UID of mail).
(2) Copy three mails to X/A1, add tag of "To Do"(blue) to three mails.
    X/A1 : change mail status
    X/A2 : opened before change at X/A1
    X/A3 : not opened before change at X/A1. opened after change at X/A1
    mail-1 : to make mail-1 last accessd mail, to keep other's Unread status.
    mail-2 : mail of non-highest UID
    mail-3 : mail of highest UID
(3) Copy mail-1(lowest uid) to X/A2, X/A3, copy mail-2(next uid) to X/A2, X/A3,
    and copy mail-3(highest uid) to X/A2, X/A3 (to keep same order).
    At all 3 folders, click mail-1(last accessed mail, to keep Unread of 2/3).
    Check all mails in all three folders, and confirm "same status/tag".
(4) Restart Tb with IMAP logging, and Click X/A2, then click X/A1
(5) At X/A1, add tag of "Important"(red) to all three mails,
    change mail-2/mail-3 to Unread, and click mail-1.
(6) Click X/A2, check thread pane(don't touch mail, not to change read/unread)
(7) Click X/A3, check thread pane(don't touch mail, not to change read/unread)
What status/tag(color) is seen for mail-2/3 in X/A2 and X/A3?
(8) Work Offline, go back to Work Online
(9) Click X/A2, check thread pane(don't touch mail, not to change read/unread)
(10) Click X/A3, check thread pane(don't touch mail, not to change read/unread)
What status/tag(color) is seen for mail-2/3 in X/A2 and X/A3?
(8) Terminate Tb, keep backup of log.
Note: above is similar procedure I used in test of Bug 450246 for tag.

As test is relevant to X/A1, X/A2, X/A3 only, irrelevant logs can easily be removed by text editor. To reduce irrelevant logs since first, I recommend to disable "Check for new messages upon sartup/every NN minutes" when getting log.

Umang, no need to execute test of comment #9.

I could observe that \Seen/no \Seen and addition/removal tag at other folder is immediately reflected to any other folder with Tb 3.0.3 like before.
Reflection to Inbox was after several click of Inbox. It's probably by "cached MsgDb after a while"(still cached, then "uid 1:* flags" is not issued).

When I tested comment #6(and bug 450246 #13 to #15), I saw "too much connections" from Gmail IMAP because I used both Sm2 and Tb3 for same Gmail IMAP access with "max cached connections=5"(Sm2: 2 Gmail IMAP, Tb: 1 Gmail IMAP) and I repeated termination/restart of Tb for testing. Such error may produce phenomeon of "unclosed MsgDB or close failure of MsgDB".
I'll continue to check it in bug 450246.

What I saw in comment #6 was possibly phenomenon like next;
- Until "select Inbox" happen again, UID fetch 1:* (FLAGS) is not issued again.
- If connection error occurs on connection for S-INBOX, folder switch by
  "select other-folder" at the connection doesn't occur not so easily.
- "MsgDB is not closed due to soemthing" may produce similar issue,
  because folder open is not invoked.

Run one to two hours with logging, and check whether "number of opened .msf" increases without close, or not, please. (log of "increase as if infinite" was attached to a bug, although it looked local folder/rss/news case.)

There is no need of log data itself. Your check result of "number of opened .msf at each MSGDB:5 logging(looks periodical) increases as if infinetely or not" and of "close of .msf/MsgDB is logged as expected or not" is sufficient.

(In reply to comment #14)

If you use Tb 3.0.2 or later, bug 540214 is fixed. So, I think check with enabled is better initially, if enabled is your default setting for daily use, because folder access/MsgDB open doen't happen unless you manually click folder if disabled.
If something wrong around MsgDB open/close will be found, test with disabled will be required for diagnosis, to check whether other component such as Gloda, auto-sync, is culprit or not.

If problem of "MsgDB is never closed" occurs, the NNN increases as if infinitely. So, I'm confident that such problem doesn't exist in your environment by your answer. Thanks for your log analysis.

Note: "PPP hdrs in use" is probably similar to "PPP mails are held in the folder".

Steps to reproduce:

When reading an email or emails on another device/location, those emails are marked as read on that device and the IMAP server. I am using gmail & an IMAP connection on both Thunderbird and the other device.

Actual results:

When Thunderbird is left open, it sometimes takes 2-3 hours or even longer for Thunderbird to mark those emails as read. I have tried clicking on the "Get Mail" button to refresh the IMAP folder but TB still doesn't mark those emails as read. I have checked to see whether those emails are flagged as read or unread but using the gmail web client and they are indeed being marked as read but Thunderbird will not refresh their read/unread status.

Expected results:

Each time Thunderbird attempts to get mail it should check the status of read and unread emails from the IMAP server and mark those emails as read if applicable. The only way to force TB to refresh the read/unread status is to completely close TB and re-open which is obviously very annoying.

If the mail is "a mail in a conversation of Gmail which contains multiple mails", phenomenon of bug 478996 occurs. Don't use "read/unread status of a conversation at Gmail Web interface" as evidence of "read status or unread status of a mail", unless it's sure that the conversation of Gmail has single mail only or that all mails in a conversation of Gmail has same status of read or unread.

See also bug 518581, if Gmail IMAP.

To avoid excess network traffic due to "fetch of flags of all mails in IMAP folder upon each folder access",
(imagine 1,000,000 mails in a folder * 10,000 folders, new mail check of all mails folders each one minute)
Tb currently relies on "flag status change notification from server via IDLE", but many IMAP servers including Gmail IMAP unfortunately don't look to do so.
Following is a possible workaround at Tb in your case, if your any IMAP folder is never huge.
  - Disable IDLE command use
    Max chached connections = 1
    (I think Smart Phone's setting is similar to: no IDLE, max=0)
    (Tb doesn't permit max=0. Always uses default of 5 if max=0 is specified)

Interestingly, if I read an email in TB, that email is almost instantly flagged as read on my iPhone.

There is still a delay of many hours if I read an email on my iPhone or web client to be marked as read in TB.

Did you restart Tb after the setting change?
Effect by the setting change is not immediate, so restart of Tb is needed to see effective or not.

Any developper can repro the bug easily: create a Gmail account (they are now free, and don't need sponsorship anymore; beta have been close, and official product have been launched years ago), configure two different Thunderbird profiles to access the same Gmail account, send one email from one box to the other one, read the mail on both, mark the mail as unread on one, and click GET MAIL on the other one, you will see that email is marked unread only after restarting "the other one".

You don't need huge amount of data from users, strace or backtraces. Any dev can produce desired amount of logs for free, any time, and from any country (yes ... I had country specific issues with Google in the past - this bug is NOT one of them). To dig deeply into client-server communication, tcpdump often helps.

Thunderbird is a free software. And dev always remind users that they are volunteers. But the products of the Mozilla fundations have a reputation to defend; they slowly became popular, and are now used by many people ... not only geeks in the cave using Linux for religious reasons; Thunderbird is used by people why have serious work, and who consider Thunderbird as a work tool. This means ... the tool must meet minimal requirements, and must work at least, as good as other concurrent products. And since mid 2013, thunderbird have serious issues. It does not sync properly messages status, and does not work at all anymore with Google Calendar (yes I know, it's not Mozilla Fundation who was responsible for Google Calendar Exchange server shut down; but the moz team could have worked on making TB compatible with an other protocol). Now, TB have become a poor mail reader not even able to track a READ STATUS, I can not use PGP encryption at all (since TB3, or maybe even TB2, I forgot), and it can not let me use my calendar any more. I wonder why I have not yet changed MUA.

Dev always claim that ... they work for free, and are free to choose what to work on, which snipset of code they want to have fun with. By letting users down on basic features, users will get bored of the product. This bug is one of the few that I consider critical and urgent. Last week I was trying to configure an old Nokia Symbian S60 for Gmail sync; in my research, I have found several articles saying that Gmail closed the Exchange access, and that Mail for Exchange for Symbian is now deprecated because of Google choices; the articles was also doing an overview of other affected products; MFE@Symbian was considered as a small loss, because Nokia themselves left down Symbian, and they officially stopped supporting Symbian S60 phones. The article also mentionned that Thunderbird was also affected, and that is was a shame for such a populat product to not publish a serious work around within days. A WA should have been proposed in days; it's now one year, and TB still does not compensate the loss; any mobile phone (included Linux based And...

It's pretty simple. Merely one of next,
  (i) Your problem is not this bug. Your problem is absolutely different problem from this bug.
  (ii) Your problem is this bug, but your operation is wrong.
because this bug is for following problem(and only for following problem).
  Server doesn't notify flag change via IDLE,
  so Tb can't know flag change status of already fetched mail via IDLE.

Example of (i) :
- If CONDSTORE is used, UID fetch 1:* (FLAGS) (CHANGEDSINCE ...), UID fetch Highest:*
  (CHANGEDSINCE ...) is used by Tb. This may produce problems in getting flag status of already
  fetched mail.
  Read bug 885220 for IMAP flow for this, please.
  This kind of issue is one of reasons why bug 912216 was opened.
  Note: Both bugs are alreeady pointed in this bug.
Example of (ii) :
  - IDLE command is issued after end of IMAP command execution at cached connection.
    "Use IDLE command" setting is for "issue IDLE or not, at end of IMAP command execution".
    "Use IDLE command" setting is never for "terminate current IDLE status at a cached connection".
  - Upon periodical new mail check, if an Mbox is already selected at a cached connection.
    Tb uses "uid fetch KnownHighestUID:* Flags".
    Inbox is selected at a cached connection always, except when max cached connection=1.
  Even though these, even though an Mbox is still IDLE status at a cached connection after
  disabling "Use IDLE command" setting, or even though an Mbox is still selected at a cached
  connection after some actions, write useless comment to a bug.
  Note:
  "go Work Offline" step of operations which is written in this bug is for;
     Force close of all cached connections, in order to force Tb to do "open connection, login,
     select Inbox(and other Mbox), uid 1:* fetch (flags)" again after "go Work Online".
  "disabling CONDSTORE support" is for;
     Force Tb to use "uid 1:* fetch (flags)" instead of "uid fetch 1:* (flags) (CHANGEDSINCE ...)"
     even when server supports CONDSTORE extension.

Although, I am slowly getting away from using Gmail as my main provider, since I do not really care for people having easy access to see all of my e-mail, not that I have anything to hide, but on principle. I have just been using my website's e-mail service instead.

Dear WADA,

How do other email clients deal with this situation on the commonly huge IMAP folders of Gmail ?

I think this is a rather critical bug of Thunderbird. As you say, "some major IMAP servers don't notify flag status change via IDLE", and Tb should be able to deal with this situation OOB. If I understand correctly, the workaround only works well with small IMAP folders.

Are there plans to fix this 2.5 years old bug ?

Would it really be too resource intensive to simply perform these additional steps each time Thunderbird checks for mail updates? Maybe that is what every other email client does and that is why they do not have this problem. Thank you.

A possible way.
- Install "Custom Buttons" addon, add your own Toolbar Button labeled "force sync".
- Put small JavaScript code like "click Work Offline, reply if required, wait for a while, click Work Online, reply if required".
  /*CODE*/
  // var MenuId="goOfflineMenuitem" ; // Firefox
      var MenuId="goOfflineMenuItem" ; // Thunderbird
      var Menu=document.getElementById(MenuId) ;
      var Status=( "true" == Menu.getAttribute("checked") ) ; // atribute value is String
      var OnCommand=Menu.getAttribute("oncommand") ;
      // oncommand="MailOfflineMgr.toggleOfflineStatus();"
      if( false == Status )
      {
          // go Work Offline
          eval(OnCommand);
          // do reply to dialog for download now,
          // go back Work Online, and do reply to dialog for send unsent messages
          // setTimeout(GoBackOnline,3*1000) ;
       }
      else if( true == Status )
      {
         // go back Work Online
         eval(OnCommand);
         // and do reply to dialog for send unsent messages
      }

This version doesn't do automatic reply to confirmtion dialog, doesn't do Toogle Back to Work Online mode.
So, you have to do: 1. Click the button, 2. No to dialog(download now), 3. click button, 4. Cancel to dialog(send unsent mail).
This is merely an example of your own pretty small Addon by your own ToolBar button.
id of menuitem, toolbarbutton , attributes of them etc. can be pretty easily known using DOM Inspector.

In case you're not aware of it anymore, going offline and back online does not resolve the issue. At least for me. The only thing that does help is restarting Thunderbird, which I have to doo every few days when I deleted something either in the web mailer or my smartphone (K9 mail), with both work fine the other way around.

This seems to be the Mozilla way of dealing with bugs: Blame it on the others, no matter how. While my comment may not be constructive, neither is yours. We're living in a real world that doesn't always work as designed.

Funny. It sounds that your Thunderbird is not standard one...
IIUC, IIRC, after Go Work Offline, Tb closes all connections, and after Go back Work Online, Tb executes login sooner or later, and after login, Tb opens Inbox(and others if requested) for new mail check by Biff, or open Inbox (or an Mbox) when selected, and upon first select Inbox/Mbox at a cached connection, Tb always issues "uid 1:* fetch Flags()" unless CONDSTORE is used. This is confirmed many times by getting IMAP log.
If "uid 1:* fetch Flags()" is used, Tb should know all flags of all mails in an Mbox.
If not, it usually means that your Thunderbird is not properly configured.

Have you checked IMAP protocol level flow by yourself?
Do you correctly disable CONDSTORE support as stated in this bug more than one time?
Or if Inbox, did you do required "click Inbox while other than Inbox, for example account, is selected at Folder Pane"?
Because "new mail check by Biff" is not immediately invoked after going back to Work Online"(invoked at next new mail check interval), "time lag" exists between "going back to Work Online" and "first new mail check after going back to Work Online".

> Thunderbird is the closest, unfortunately.

- Send Without Save(Copy Sent to Current has equivalent functionality and seems to be fine)

Once I disabled the above extensions, using a cyrus imapd 2.4 IMAP account that supports IDLE and CONDSTORE, Tbird changes from often requiring the Offline/Online trick, to usually updating immediately, sometimes requiring a folder change to see the updates, and occasionally requiring a Compact to see the updates. But as far as I have seen so far, Tbird now never requires Offline/Online to sync the folder, which is a huge improvement.

Disabling CONDSTORE further improves matters and Tbird more often (always?) updates the folder immediately. Obviously that is related to the separate CONDSTORE issues though.

I don't know about Thunderbird, but I see the same thing (going offline does not work, I have to restart) in "standard" Seamonkey, and have done through many versions of Seamonkey. In Seamonkey it is actually more annoying, because you need to shutdown all Seamonkey windows (i.e. browser windows and everything, not just mail and news windows).

IIUC, there is no difference between SeMonkey and Thunderbird, as for phenomeon of this bug.

(a) As repeatedly written, after go Work Offline the go back Work Online, explicit folder open by new folder click is mandtory to force server access again. When did go Work Offline the go back Work Online, did youa ctually do it?
      - If Inbox is already selected at folder pane when "go back Work Online" is executed,
          click account then click Inbox again at folder pane.
(b) As repearedly written, Gmail IMAP started to enable CONDSTORE and Tb's CONDSTORE support is enaabled by default.
      When CONDSTORe is used, Tb may not use "uid fetch 1:* flags" or "uid fetch 1:* flags CHANGEDSINCE nnnn".
      Tb may use "uid fetch <HighestUID>:* flags" or "uid fetch <HighestUID>:* flags CHANGEDSINCE nnnn".
      As repearedly written, to force "uid fetch 1:* flags" always in recovery operation for this bug,
      disbaling Tb's CONDSTORE support is needed for problem determination.
      Did you properly disabled Tb's CONDSTORE support?
      Read thru Bug 912216 and bug 885220, al repeatedly written.

Further, get IMAP log and check imap level flow by yourself, before adding comment like "annoying ..." which will never help activity for resolving problem.
Problem of this bug is pretty simple.
1. To know flag state change of already fetched mail of UID=NN<CurrentlyHighestUID, one of next is needed.
    1-1. flag staae change notification for the UID=NN from server via unsol response to lIDLE for selected Mbox.
            => Tb expects it, but maany IMAP servers including Gmail IMAP won't do this.
    1-2. uid fetch NN flags at connection where the Mbox is selected.
            => Tb uses "uid fetch CurrentlyKnownHighestUID:* flags" for new maail check of already selected Mbox.
                  So, flag state change of UID=NN can not be known untill "uid fetch 1:* flags" is issued again for the Mbox.
2. Recovery operation stated in this bug is simply "a procedure to try to force uid fetch 1:* flags".
    2-a. Unless you explicitly click Mbox, connection with server for the Mox won't be opened immediately.
            Without connection with imap server, any "uid fetch ..." won't be issued for the mbox by Tb.
    2-b. Even when connection for the Mbox is established and the Mbox is selected at connection,
             Tb may not issue uid fetch 1:* flags". Tb may use "uid fetch HighestUID:* flags ...".
             Even if "uid fetch 1:* ..." is used by Tb, it may be "uid fetch 1:* CHANGEDSINCE nnnn"
             where nnnn is too large(may be newer than MODSEQ for flag change of UID=NN).

Well, I disabled it in mail.server.default.use_condstore - there is no ...use_condstore setting for the account, so I guess Seamonkey doesn't implement it per account - or should I just create the setting?

> Further, get IMAP log and check imap level flow by yourself

Unfortunately that'll have to wait for another day.
But testing a few more times I discovered that it actually does work, just only every second time - i.e. I have to do "offline>online>other folder>back to folder>offline>online>other folder>back to folder" before it updates.

The implementation is identical between SeaMonkey and Thunderbird. If there is no server#-specific setting mail.server.id#.use_condstore then mail.server.default.use_condstore is used. Thus, setting mail.server.default.use_condstore to false should disable it for all configured IMAP servers unless specific preference settings for that server override it.

It's perhaps "connection loss during IDLE".
  IDLE -> Sm/Tb(and server) enters "receive state" -> Work Offline -> Tb closes server connection(Socket, TCP/IP level)
  Tb perhaps closes IMAP connection. But for SeaMonkey, this is perhaps "connection loss during IDLE".
  By click of Inbox again, Sm tries to send DONE(enters Send mode)
  -> because TCP session is already closed by Sm, nothing is sent to server, and Sm waits for timeout.
  -> go Work Offline/Online again -> send of DONE fails and imap connection is normally closed in Sm
  -> by next click of Inbox, TCP session is established and imap connection is established
It seems that error detection code is different between SeaMonkey and Thunderbird.

> so I guess Seamonkey doesn't implement it per account - or should I just create the setting?

There is no need of guessing. "CONDSTORE is aactually used or not" is always clearly known pretty easily by simply looking imap log.

All this discussion is very well and good, but how do we work around this problem?

I'm deleting e-mails from Gmail on my iPhone and still seeing them hours later in Thunderbird.

I'd really prefer not to do this by hand every hour.

What is the prescribed fix / workaround?

Do you read about a workaround of "max cached connection=1"?

If shared with iPhone, I believe mail volume, number of mboxes, frequency of new mails, new mail volue, are not so large,
If so, "max cached connection=1", "disable IDLE", "adequate new mail check intervlal", can be used.
Needless to say, "disabling CONSTORE" is mandatory.
1. Click other than Inbox(call FolderX) -> SELECT FolderX -> Inbox is unselected at only one connection
2. Soner or later, new mail check occurs -> SELECT Inbox -> Inbox is selected at only one connection -> uid fetch 1:* Flags
3. When you need to snch flsag state with Gmail IMAP and iPhone, click FolderX, then click Inbox
     SELECT FolderX -> SELECT Inbox -> uid fetch 1:* Flags for Inbox is issued.
     As I repeadly staated, workaround explained in this bug is to force this "uid fetch 1:* Flags" for Inbox.

Another way: Use Inbox as mail drop, mail tray. Don't use Inbox as mail repository for log time.
                       Becuase of IMAP many Mboxes are lready supported. There is no need of folder named "Inbox" for mail viewing.

Because Inbox is mbox where new mails arrives, Tb always keeps Inbox "selected state" at a cached connection for Inbox only, and kepp Inbox open.
This is a reason why "uid fetch 1:* Flags" is not issued for Inbox while Tb is running.
If other folder than Inbox and Trash, connection for a FolderX is stolen by other FolderY when other FolderY is opened.
So, "max cached connections = 3 with folder switch of some folders someties" usually forces "uid fetch 1:* Flags" of FolderX, FolderY.

Why no problem in iPhone :
   Because of small/mobile device, connection is not kept for long time, and number of connections is usually one..
   Upon mail reading, login, SELECT Inbox, "uid fetch 1:* Flags" is executed.

Do you understand workaround of "max cached connection=1" and understaand IDLE?
If "max cached connection"=1, and if "other than Inbox, call FolderX" is selected at the only one connection, IDLE is effective only for FolderX. If Inbox is de-selectied at yhe only one cached connection, IDLE can do nothing on Inbox. If workround of "max cached connection"=1 is used, "IDLE works on Inbox sometime but IDLE won't work on Injbox other times" is pretty confusing, and it may produce useless bug open at B.M.O.

> I don't believe anybody is able to fix this issue (and others) without rewriting it all. If only I had more time.

You are absolutely free to believe anything.

Have you read and understood all bugs pointed in Bug 912216?
Because Gmail IMAP started to support CONDSTOREl last year, "solution of this bug utilizing CONDSTORE" is possible. As known by bugs pointed in Bug 912216, code change needed for the solution is not so huge. Rather, relatively small change than we thought.
Neeedless to say, as known by Bug 912216, there is problem in current CONDSTORE support in Tb, so it should be resolved.
And, for better solution, QRESYNC support by both Gmal IMAP and Tb is needed.

Thanks WADA. I read the whole thread, after reading another long thread that was closed as a duplicate of this one, so by the time I got here I was very tired and just wanted deleted messages to go away.

Max cached connections was the only part in all that reading that I understood, so I have max connections set to 1. It slows down my client a bit, but I can accept that.

> If so, "max cached connection=1", "disable IDLE", "adequate new mail check intervlal", can be used.

I didn't understand what "disable IDLE" was until I started writing the proposed steps below. I still don't understand what "adequate new mail check interval" means. Bear in mind, I don't understand the client as a developer, I understand it as a casual user, so I need click-by-click, press-by-press, key-by-key instructions. I suspect most other users who would come across this thread would need that too, and ideally it would be pinned to the top of the bug. I've made an attempt at documenting the prescribed workaround below.

> Needless to say, "disabling CONSTORE" is mandatory.

I don't understand what that means, so it's not included in the steps below.

I did an experiment and I believe "sooner or later" can be replaced with "Restart Thunderbird." This is my attempt at documenting the workaround step by step:

FIRST, RECONFIGURE YOUR ACCOUNT:
1 - From the main Thunderbird screen, select "Tools" menu > "Account Settings" to launch the Account Settings window.
2 - On the left side of the Account Settings window, select "Server Settings" under your Gmail account name to view the Server Settings page.
3 - On the Server Settings page, press the "Advanced..." button to launch the Advanced Server Settings popup window.
4 - Set "Maximum number of server connections to cache" to 1.
5 - Deselect the checkbox for "Use IDLE command if the server supports it."
6 - Press the OK button to close the Advanced Server Settings window.
7 - Press the OK button to close the Account Settings window.

EVERY TIME YOU WANT TO REFRESH THE INBOX:
1 - Select the "Sent Mail" folder (or any other subfolder under the affected account).
2 - Close Thunderbird, including all mail viewing windows.
3 - Start Thunderbird.
4 - Select the "Inbox" folder of the affected account. Thunderbird should completely refresh the Inbox.

Tb already has button for "Refresh folder from scratch". It's called "Repair Folder" button :-)

> Better yet, add a Refresh button in the same row as Unread, Starred, Contact, Tags, and Attachment?

You are right.
There is no way to intentionally close mail folder in Tb.There is no way to force de-select of Mbox at a connection.
There is no way to force "uid fetch 1:* Flags" to recover from this bug by simple/easy operation.
Purpose of any workaround stated in this bug is : force "uid fetch 1:* Flags" for Inbox.
    Go Offline/Go Online : Force logoff -=> Tb has to do login, SELECT Inbox, uid fetch 1:* Flags
    max cached connections=1 : FolderX steels connection from Inbox => When Inbox is accessed, Tb has to do SELECT Inbox, uid fetch 1:* Flags
If "close/reopen folder" like button/menu will be implemented, it's helpful for this bug.
But there is no need of such button in usual use. Button only for working around problem(in this case, in both Tb and Gmail) is not usually implemented.

About IDLE setting : Server Settings/Advanced
About CONDSTORE : read Bug 912216, please.
About "adequate new mail check interval" :
   If "a few new mails per an hour", I believe "Check new messages Every 1 minute" is usually not mandatory.
   If "10000 new mails per an hour", I believe "Check new messages Every 1 minute" is not needed(rather annoying),
   because you can know about many many new mails upon each mail viewing. :-)

If I understood your headings, I can safely reduce all of your steps to the ones I left in my quotation. I see deleted mails almost every day in my primary mailbox which is not Gmail. I just need to restart Thunderbird and everything works nicely again. No other configuration is required for this to work. Still it's cumbersome to restart applications to repair them, it might as well crash every day. This really should not be necessary at all.

Still seems to be an issue for me with Gmail. At least I assume this is the same issue. In my case, I filter all emails into folders (or "labels" as Gmail calls them) on the server. So all emails sent directly to *my* email address go to a folder/label called "Me".

== Steps to reproduce ==
1. Open Thunderbird.
2. Open arbitrary email app on phone/other computer. Send email to Gmail account.

== Expected results ==
Within seconds, Thunderbird displays the new mail in the "Me" folder, complete with a notification.

== Actual results ==
<nothing happens>

== Completely manual "workaround" ==
Click the "Me" folder. Thunderbird instantly displays the new message.

I note that even clicking "Get Messages" doesn't pull down the new message. What the heck? Clicking the folder gets a new message from the server but clicking "Get Messages" doesn't?

I have tried what I think is everything from this thread: disabled IDLE and changed max_cached_connections to 1. My CONDSTORE was actually "false" by default (Thunderbird 38.2.0 on OS X) so I left that as-is. I did a complete Exit of Thunderbird and restarted. No difference whatsoever.

I have had 2 Thunderbird 45 instances for the same Gmail account open in the last weeks, viewing the All Mail folder while I was deleting mails from that folder. On several occasions, I noticed after deleting and/or tagging mails from one instance that the other instance wasn't updated. The deleted mails would still show, and would keep showing even after "Get Messages". There was no activity shown, and even Activity Manager showed nothing going on. If I remember correctly, this fixed between 1 and 5 minutes after going back to the outdated instance (Thunderbird would take the initiative to update, even though it had been asked before).

It seems like after a while Thunderbird goes in some kind of sleep mode, and has trouble waking up from that, but it hasn't happened often enough for me to explain the precise conditions needed for this to happen.

I do not fully understand Summary and am unable to parse several comments, and as it would take an eternity to go through all other comments, I will assume that the symptoms I experienced are results of the bug reported here and add a vote.
