Comment 75 for bug 631395

After upgrading to the new amd64 package, I can observe the following behaviour:

Starting Evolution online, new emails are not synced and the refreshing progress remains at 0%, "looking for new messages" remains at 100% without disappearing.

Starting Evolution offline and then connecting to the server with the connection symbol results in several error messages (Could not connect to the server), after clicking OK until the messages disappear, same behaviour as above, nothing happens. When I then click on an other folder (i.e. "Sent Items"), the refreshing process starts and finishes successfully. Clicking then on the Inbox starts the refreshing process and after reaching 100%, the message disappears, the message concerning new messages remains (with 100%) and new mails are not displayed. The terminal windows shows the following message: "evolution-mail-Message: Error occurred while existing dialogue active: column folder_name is not unique".
Clicking again on an other folder and back on the Inbox (while clicking several times OK on the "could not connect to the server" messages) results in displaying the new messages, on the terminal window I see the message "(evolution:2561): camel-exchange-provider-WARNING **: got_folder_props: 7"

When I then open an email (and after several error messages "could not connect to the server" again) and try to forward it, no email is sent and the terminal shows the following message: "(evolution:2561): camel-exchange-provider-WARNING **:
No GC: could not unmangle sender field".

Exiting Evolution is still not possible (the status message about the saving of the account remains at 0%).

I'm extremely frustrated, because I was desperately waiting for the MAPI connection, which does not work also, and now I can not even use the Exchange Server connection anymore.

Any hints are more than appreciated, and if I can provide debugging information, please advise me, because I'm still an Ubuntu newby.
