Thunderbird 115 authentication problems

Yesterday, thunderbird 115.3.1 was automatically installed. Since then, all my Microsoft accounts do not work anymore. I think the problem is this: https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202.

I've been messing around with the imap url, smtp server and oauth2 settings for a day now, without fixing the problem.

I have one profile with multiple e-mail accounts (more than 10, under which gmail, hotmail, live and outlook accounts) in it. They used to authenticate with oauth2, but now I cannot get that to work anymore. I can get receiving mail to work (even with oauth2), but sending mail (smtp server settings) are behaving different and unexpected every time. Some accounts can send an e-mail, and after restarting thunderbird not anymore. Other accounts have not been able to send an e-mail at all. I'm talking, for instance about 2 Live mail address behaving differently, even with the same settings (url, protocol etc).

Another major pain is the following (and I've not read about other people having that same problem, yet): I've logged into the outlook popup and given the thunderbird app access rights again, but after restarting thunderbird about the half of those credentials are gone again (in thunderbird settings Saved password). And I can start all over again?

What can I do?!

Have you sorted it out?

Some of my problems are fixed, some not:

  • I can get mail now for multiple accounts, might even be able to use oauth2 for some
  • stored imap credentials are persisted since thunderbird bug fix in 115.4.1
  • I still can NOT send mail for all Microsoft accounts (smtp still not working from thunderbird)
  • multiple stored smtp server passwords are still not persisted well

Where could I report this so that thunderbird can fix it? I thought this forum was for this kind of questions, but since I got no replies at all...
