Hello,

since a while my Thunderbird stopped downloading any mails. Instead it always asks to type in the passwort again but also after doing that, it just doesn't load any new mails. But I also never got any other error message. I use two different email providers (gmail and gmx) and neither of them work any more. I tried updating my Thunderbird. Now I have version 91.10.0 (64-Bit) installed but it still didn't get any better. Then I thought it might be due to the OAuth 2.0 thing that gmail now uses (which still wouldn't explain the problems I have with my other email provider), so I checked for the necessary preferences and the passwort it was indeed not set to the authentication method OAuth. I changed it and then the prompt asking for a passwort changed to the one from gmail. But even after typing in the correct data and clicked on "allow" for Thunderbird to use the necessary gmail data, it can't connect and gave an authentication error. Now that I tried to make a screenshot, it doesn't even do that anymore.

I use Windows 10 Home and I didn't change anything that could have caused this and all the account settings should be correct.

So, I don't know what to do anymore and I didn't find any other threads fitting this problem. Can someone please help me?

Cheers, Nadja
