Set up Existing email address Tests are good, but when clicking on done I get "Error Creating Account Incoming Server Already Exists"? Can't update any of my accounts??
Updated all my email passwords on the AT&T server (8-emails) and updated the passwords on Thunderbird and none of them work. Tried Set Up Your EXisting Email Address and all the accounts test correctly, but when I click on the "Done" I get an Error Creating Account Incoming Server Already Exists" and NONE of the accounts will update??

There's no need to add the accounts if they're already set up in TB, but instead of entering the new passwords, remove the old passwords from Saved Passwords in Options, create a secure mail key for each account, then enter the key when TB is restarted and you're prompted to enter a password.

If you do add accounts on the same server, give each one a distinct Account Name in Account Settings to avoid the 'already exists' error.
