I'm trying to set up Thunderbird on my new Windows 11 computer. Every time I try to setup outlook.com I a get a message saying "Authentication failed. Please check the username and password" The version of Thunderbird I'm using is 144.0.1. I even went to outlook.com on line and changed to a new password and it still will not work. All my other email accounts are working perfectly.

Outlook works perfectly on my old windows 10 computer, but it will not work on this one.

Any help would be appreciated.

Thank you,
