gmail
Hello. I cannot add gmail to Thunderbird. Windows 7, setting OAuth2, al is well until I allow TB to access my gmail account. Error following password check: "Unable to log in at server. Probably wrong configuration, username or password". No problems with Win 10. Same settings as in my Win 7 machine. Thank you for your help. Borys Brezden

Windows 7 is the problem. Gmail's OAuth2 won't work. You can use Normal Password authentication with an app-specific password instead.
