I am trying to get my emails on a new computer via Thunderbird. I have installed Thunderbird on new Windows 11 PC. I have TB on old computer. I use my existing info, TB finds the credentials but when it goes to do it's thing I come back with error messages saying" Unable to long in at server: Probably wrong configuration, username or password. The info is correct. Please any info would be appreciated. I have been working on this for hours and am exhausted. Error attached.

Create a secure mail key on the AT&T site and use it in TB instead of the account password.
