Forum says you need a screenshot to help diagnose but Thunderbird doesn't allow screenshot of settings... So, Server Settings:

 Server Type:  IMAP Mail Server
 Server Name: imap-mail.outlook.com  Port: 993

Security Settings

 Connection security:  SSL/TLS
 Authentication method:  Normal Password

Running Thunderbird 115.10.1 (32 bit) Outgoing Server (SMTP) Settings Microsoft Live Hotmail - smtp-mail.outlook.com (Default) Windows 11 Home V 23H2

I've tried everything I can think of and read/tried lots of suggestions including turning off firewall, password changes, etc. I don't recall any updates or changes to anything when the problem started several days ago. Exasperated. Thanks for any help.

(PS - I do, on occasion, send a few $ to Mozilla. ;-) Thanks for your time.

David - just messed around and got it working. Wasn't password, seemed to be something about the outgoing server settings which I changed to a different default setting using your advice. ANYWAY, it's working and It's difficult for me to pass a hug across the ether so you'll have to do with a heartfelt THANK YOU!

MS sent a notification in late August of changes effective on Oct 1, so I imagine that's your situation. Try these: - incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 (assuming IMAP) - outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2

Wow David - I'm ALMOST there. Incoming messages now working - woo hoo. Tried changing settings on outgoing server but not working, just hanging. Maybe because the "Oauth2" didn't show up as an option when I changed to STARTTLS - so I selected Normal Password... Any ideas?

Wait - I was able to use a different default outgoing server that had Oauth2" so am using that and now receiving a different message - that my MS password isn't working. So doesn't look like a Thunderbird issue at this point. ?? But I'm able to receive Outlook emails so now am confused by that.

some users found they need to exit and restart. I had a similar problem and found that clicking 'edit' again on SMTP server that the option worked.

Yeah, the "edit" seemed to be what did it for me too.
