Hotmail oAuth2Error "Authentication failure: unknown user name or bad password"
My Hotmail account suddenly stopped working today (was working yesterday). Thunderbird shows a popup saying authentication failed, but doesn't ask me to try a different password (not that I changed it recently).
The error details are only visible in Error Console:
Got an error name=oAuth2Error, the server said: Authentication failure: unknown user name or bad password.
Using server: outlook.office365.com, port 995 (POP) user name: ****@hotmail.com SSL/TLS, OAuth2
