Thunderbird fails to log into outlook.com now that 2FA is required

I have not been able to get Thunderbird to work with my outlook.com email address since MS requires 2FA, for me about 3 days ago. My server configuration is :

W10/32 bit fully patched Thunderbird 128.2.3esr (32 bit) POP Mail Server outlook.office.365.com, port 995 my MS "user name" which is my email xxxx.outlook.com SSl/TLS OAuth2

       In SMTP Server 

outlook.office365.com 465 SSL/TLS OAuth2 xxxx@outlook.com

The error message I get with this config says "Thunderbird could not connect to server outlook.office365.com; the connection was refused".

I DO NOT have an office365 account.

Logging to www.outlook.com with my UN (=outlook.com email address) and password WORKD. Although the lack of a way to turn off the MS spam filtering makes it useless. I have put some MS thing on my phone and I have to do some 2FA thing when bringing up www.outlook.com.


Help please.

the outgoing server should be smtp.office365.com, STARTTLS, port 587 Oauth2

Changed the smtp server, port etc as David said.I still get the same connection refused message when I try to get new messages. I edited the smtp config, exited TB, closed my "mail" window with www.outlook.com, waited a while (short while) and restarted TB. No Joy.

Friday update: Actually some joy. I discovered that sending mail from thunder bird, with the settings David suggested, does work. In fact, after Outlook does a 2FA to my phone I can send mail for some length of time, perhaps until I reboot TB (?), without repeating the 2FA dance. BTW, the 2FA I'm seeing is where outlook shows a 2 digit numbers and my phone shows three 2-digit numbers. Tapping the one corresponding to the one outlook shows finishes the login.

Still no luck receiving mail from outlook. I get the connection refused every time I try to get new mail. The outlook.com web site, such as it is, does let me see my new mail except for what it puts in junk and, I think, there are mails that outlook/MS is deleting even before the junkmail filter.

outlook.office.365.com for incoming server should be outlook.office365.com (no dot between office and 365).
