OAuth2 is REQUIRED now for MS Outlook email, now I get prompts for passwords
I got an email from Microsoft saying my Live.com or Outlook.com email accounts won't be supported in Thunderbird UNLESS I change the settings to OAuth2 in incoming and outgoing server settings.
I even REMOVED the email account and re-added it making sure it was OAuth2.
But for my live.com & outlook.com email accounts I continually get prompts for passwords from Thunderbird. Sometimes I can't even click the RED X at the upper right to shut the prompt down. I just happens over and over until I give it what it wants.
I am tempted to shut down all Microsoft email accounts and switch to Gmail.
I have Thunderbird version 115.12.2 (64-bit) I used Windows 11 23H2 build 22631.3810 Windows Feature Experience Pack 1000.22700.1020.0
Any idea how to stop these prompts?
I like Thunderbird much more than any other email program I have ever used, and would like to keep it

I just wanted to say I was JUST ABOUT to delete most if not all of my outlook.com accounts because of the constant nagging me for passwords and then the problem resolved itself...I HOPE.
An update to Nebula seemed to fix it. I hope it stays fixed!
Fingers and toes crossed!

re :I see that nicksasso21 may be having a similar issue (but with Office365), where you asked for the Access Error Code info,
In that error console information it said: mailnews.smtp: Command failed: 535 Authentication unsuccessful, SmtpClientAuthentication is disabled for the Tenant. Visit https://aka.ms/smtp_auth_disabled for more information.
The link mentioned in error console : https://aka.ms/smtp_auth_disabled That link goes to this location - I specifically include the info on 'enable smtp': https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/authenticated-client-smtp-submission#enable-smtp-auth-for-specific-mailboxes
The user discovered they were not enabled for SMTP. After switching it on - all now works. So I managed to help them sort out their issue.
Let's recheck your errors again In Error console. After clearing and restarting thunderbird then do a send - but create a new write message - do not use a message presaved in drafts - do not save in drafts. Then check error console - upload an image.
