Try to turn off the new Account Hub, and use the New Account Wizard instead. At the top right of the Thunderbird window, click the menu button ≡ > Settings > General > Account hub Uncheck 'Create accounts in the new Account Hub'. Also see https://support.mozilla.org/kb/automatic-account-configuration

The account hub can't be disabled in 150. State the account provider so we can confirm the settings. Some require a type of password or authentication that is different from the regular one.

thanks a lot for your quick reply. meanwhile, I installed an older version (149.0.2), which worked on an other laptop. However, also with this version the same problem. So I concluded, it can't be Thunderbird. Finally, I found that I need to enable IMAP access on the gmx account. That did it Sorry guys, for bothering you.

Kind regards
