Dear Mozilla Team, using Thunderbird I encountered a new problem regarding my Microsoft live.com account. I've had problems logging in, I'm asked for a new password. I've seen that this here seems to be the problem (and solution): https://support.mozilla.org/en-US/kb/microsoft-oauth-authentication-and-thunderbird-202 I've then tried to follow the directions given in the article. However, I cannot change my outgoing smtp settings to Oauth2 (it only gives the options "password, normal", "password, encrypted", "Kerberos", "NTLM" and "No Authentification"). Now, I am not asked for new login data, but my mails do not appear either. It appears, that there is now no successful connection to the server (it keeps getting stuck contacting the host and sending login data; see image attached - in german). Is there any fix to this? Best Niklas
