Public bug reported: this is a KNOWN problem as I have seen similar question on the Internet and it appears that something screwed up with Thunderbird in recent updates with their OAuth2 authentication method code. I am running Thunderbird 60.9.0 which appears to be the latest available for Ubuntu (Kubuntu) 16.04 LTS
