Tried linking newly installed Thunderbird to an existing Microsoft account, It won't accept my existing Microsoft username (email address) and password, which I verified were correct.

MS settings have changed. Try these: - incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 (assuming IMAP) - outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2

Thanks very much for your reply. Unfortunately, these are the settings already setup by the program. Could this have to do with the new MS security scheme?
