Thunderbird - Microsoft email account issues

[theVman]

I have multiple Microsoft accounts with 2 factor authentication. I know the email accounts and passwords are correct as I can login using them independent of Thunderbird.

However Thunderbird continually pops up an error window with "login to server pop-mail.outlook.com with username example@hotmail.com failed. Options 'Retry' 'Enter new password' or 'Cancel'.

This happens for every Microsoft account.

I too have a similar issue.   I was able to change T-bird settings for the MS IMAP server to use OAUTH2 in the pulldown menu, but T-bird pulldown does NOT show OAUTH2 for SMTP as an option.   As a result, I cannot SEND email for my @live.com email account.    I think T-bird needs a fix.
