Thunderbird Installed Version 78.9.0, Build ID 20210322094744 on my Windows 7 SP1 computer yesterday, March ‎24, ‎2021 @ 18.16 CDT. Immediately thereafter I could no longer send or retrieve messages.

  • Attempting to send a message results in the popup message "Status: Connected to outbound.att.net", and the progress bar is green - but - eventually Thunderbird times out and returns the message: Login to account "AT&T" failed . . . Login to server outbound.att.net with username ____@sbcglobal.net failed.

NOTE THAT SBCGLOBAL IS ON THE AT&T SERVER.

  • Attempting to retrieve messages results in the message Error with account ____@sbcglobal.net - Sending of Password for user ____@sbcglobal.net did not succeed. Mail server inbound.att.net responded: Server error - Please try again later.

This is the first time this has happened after an update. Is there any way to roll back to a previous version or is there an easy fix for this problem?
