Hello all!

I have been attempting to sign into Thunderbird for the best part of an hour with no success. Thunderbird does not seem to recognise OS365 log in credentials.

I am using Automatic Recognition by entering my email address and associated password.

I get this error message after clicking "Done: "Unable to log in at server. Probably wrong configuration, username or password".

I then select "Configure manually". When selecting to set up manually, I am using the below IMAP and SMTP info:

IMAP Hostname: outlook.office365.com Port: 993 Connection Security: SSL/TLS Authentication method: Normal Password Username: name@companydomain.com

SMTP: Hostname: smtp.office365.com Port: 587 Connection Security: STARTTLS Authentication method: Normal Password Username: name@companydomain.com

But getting this error: "Unable to log in at server. Probably wrong configuration, username or password".

I am not completely lost as all credentials are correct (signed out and back in of Outlook).

System Info: Using Mac running macOS 12.4. Using Thunderbird 102.0 (64-bit)
