After updating Thunderbird to version 139.0.2 Thunderbird can't connect to my E-Mail provider! Getting error massage saying “user name or password are wrong!” It happening on my PC with windows10 Pro and the same on my laptop with windows 11 Pro. On my browser or my mobile, I can connect without any problem to my e-mail provider. After consulting my provider, his suggestion was to try installing my account again. I did but it didn’t work (same error) I tried installing older version which Thunderbird was functioning on. It didn’t work either. Even that I cleaned my PC from Thunderbird totally. To clear this point on Versions 139.0 and 139.0.1 Thunderbird function as always before. Up to now any Thunderbird update took automatically the existing setting without any problem. Any information how to solve my problem? Thanks.

Is “user name or password are wrong!” the exact wording?

That's the information (answer) I get when trying to start Thunderbird! And/or a screen demanding to give the password. Again, on my cellphone or via the Firefox browser my E-Mail provider is accessible... Thank for reacting
