My Outlook mail client was working fine yesterday & today when I attempt to send an email with Thunderbird I get an error message & asked to input my password. I enter the password for Outlook mail and then get the same error message. I delete the Outlook email client and re install and it doesn't matter the same thing happens again and again. I've read few remedies on the forum, I am able to receive mail but not send. Is there a work around for this?

MS sent messages to users about server changes. Try these: - incoming: outlook.office365.com, port 993, SSL/TLS, Oauth2 (assuming IMAP) - outgoing: smtp.office365.com, port 587, STARTTLS, Oauth2
