My MS Exchange connection stopped working in 102.8 due to the changes in OAUTH2 in that release (I found them described here: https://www.reddit.com/r/Thunderbird/comments/yqwes1/notice_to_microsoft_office_365_enterprise_users/) . I was using an application-specific password prior to this and it worked well.

In 102.8, I got the MS pop-up message to re-authenticate and I did so, using my regular MS password (the application specific password was rejected by the MS authentication). Completing this popup and 2FA then generated a message to my IT Admin to approve Thunderbird and they have done so. However, Im still getting the authentication message each time I try to connect. I also exited TB and restarted and there is no difference. So, I have these questions: - Is there anything I need to do on the client side to configure for the new OAUTH2 (my IMAP server setting is SSL/TLS and OAUTH2) - Is all the admin has to do is approve the app? (Ive confirmed with them that they have done this although I did not give a confirmation email as the MS popup says that I would). - Any other ideas or suggestions? Is there an "official" page for guiding setup of TB for MS accounts? Thanks!
