Compuserve email account and Thunderbird
From another archived post:
I have Tbird on two machines, home (Win 7) and work (WinXP). This works fine on the Win7 machine. On the WinXP machine, I get "The IMAP server imap.compuserve.com does not support the selected authentication method. Please change the 'Authentication method in the Account Settings | Server settings'".
In 'Server settings' The server name is 'imap.aol.com'. I don't see 'imap.compuserve.com' anywhere.
What to do?

AOL now uses OAuth2 authentication, which is not supported in the last version of TB for XP (TB 52). If you're restricted to normal password authentication, I think you will have to remove the account password from TB in Options, restart TB, and enter an app password that is created on the AOL site.

I've tried that. Seems like it doesn't want to go to the imap.aol.com ... it tries to go the imap.compuserve.com.
Compuserve uses the AOL servers, which would work with OAuth2 in a modern version of TB, but you will have to use normal password and an app password. There shouldn't be any references to compuserve.com servers if you've changed the settings to aol.com servers, and removed all items from Saved Passwords.
Try it in a new profile if you can't remove the spurious compuserve error. Close TB, open a Run window (Winkey+R), type
thunderbird.exe -p
to start Profile Manager.
