I am unable to access my e-mail account using Thunderbird. I just updated Thunderbird to ver. 91.5.1, but the problem was occurring under version 91.5.0. Following the Thunderbird help instructions, I successfully removed my mail account. Now, I am unable to recreate the mail account. Using <Tools|Account Actions|Add Mail Account> I entered the data to describe my current mail account on AOL.com. I can successfully retrieve my mail on AOL.com. When I attempt to set up the new mail account in Thunderbird, I get the message: "Unable to log in at server. Probably wrong configuration, username, or password." I am using Firefox 96.0.2. I do not have a firewall. I successfully uninstalled MalwareBytes.Free. I do not understand what I is going on.
