Suddenly can't access AT&T email with Thunderbird... AT&T servers are working... I can access email through AT&T/Yahoo, but Tbird only throws an error message "Server error: please try again" I get identical failures on two (2) computers, both running Tbird... Computer #1 running v.78.10.0, and computer #2 running v.68.12.1... Tbird on computer #1 upgraded to v.78.10.0 on 4/21/21... email worked until morning of 4/24/21 I have rebooted both Tbird and the computers... no joy I hesitate to uninstall & reinstall Tbird as I'm afraid of losing old emails, settings, X-notes, etc. My security suite is Norton. Any answers? Thanks

Remove the passwords from Saved Passwords in Options, restart TB, enter a secure mail key when asked for a password.
