My organization (municipal government) switched to office 365. When I try to configure Thunderbird 102.8.0 to use office 365, I can read mail but I cannot send mail. My server settings:

IMAP: outlook.office365.com, port 993, SSL/TLS, OAuth2, account robert.handsaker@townofcharlemont.org

SMTP: smtp.office365.com, port 587, STARTTLS, OAuth2, account robert.handsaker@townofcharlemont.org

When I try to send mail, it says Login to account "robert.handsaker@townofcharlemont.org" failed. Login to server smtp.office365.com with username robert.handsaker@townofcharlemont.org failed.

If I click on Enter New Password, the dialog goes away but it doesn't offer to let me enter a different password. I've double checked the password and the password is also working fine for the IMAP server.

I read the blog posts about the problems in 102.7, but I'm on 102.8. Can you help?

You should not be getting the Enter New Password dialog when using OAuth2 authentication method. Using the Password Manager - Remember, delete and change passwords in Thunderbird, find any entries that have your password and delete them all. When using OAuth2, Thunderbird saves an oauth2 token (a long string of cypher text) and not your password, so if there are entries of your password in Tbird's password vault, you need to remove them all so that it doesn't attempt to use that password to sign in using Oauth2.
