imap and smtp to outlook.office365.com over oauth2 problem

[Joolz]

Good morning,

Since yesterday january 18 2023 Thunderbird cannot connect to my company email anymore, both imap and smtp. Mail server for imap is outlook.office365.com, port 993, SSL/TLS, OAuth2. For smtp: smtp.office365.com port 587, STARTTLS, OAuth2.

On january 17 and before, all was working well with the same settings. Thunderbird version is 102.7.0 (64-bit) on an up-to-date Ubuntu 22.10. When I start TB from a terminal, I get this:

```

```

That last bit (to me) seems to indicate a client side (TB) issue. If anybody knows or can make a fix, that would be great, I much prefer TB to the MS web interface.

Best,

Joolz.

Status changed to 'Confirmed' because the bug affects multiple users.

Some extra information: `sudo apt-get install libotr5` doesn't help.

In case anyone else comes across this, the recommendation from the Thunderbird developers is to downgrade: https://blog.thunderbird.net/2023/01/important-message-for-microsoft-office-365-enterprise-users/

e.g. sudo apt-get install thunderbird=1:102.4.2+build2-0ubuntu0.22.04.1

With 1:102.7.1+build1-0ubuntu0.22.04.1~mt1 I had different line numbers in the error:

JavaScript error: resource:///modules/OAuth2.jsm, line 170: NS_ERROR_NOT_IMPLEMENTED: Component returned failure code: 0x80004001 (NS_ERROR_NOT_IMPLEMENTED) [nsIRequest.name]

In case you install thunderbird thru snap, you can upgrade to beta

sudo snap refresh thunderbird --channel=latest/beta
