I've been running Thunderbird for a few years. Recently after the most recent updates, I started to have issues with sending mail from Outlook on Thunderbird. IMAP setup by the book. But I can receive emails but can't send them. What's going on?

The obvious thing to check first is the outgoing server settings.

Under 'Account Settings' click 'Outgoing Server (SMTP)' in the left hand column. Double click the 'Outlook.com (Microsoft)' entry and check that the details are:— 

 Server Name: smtp.office365.com
 Port: 587
 Connection security: STARTTLS
 Authentication method:  OAuth2
 User Name: <your e-mail address>

That's the obvious thing. If all is as it should be, and you're using Windows, it could be anti-virus software causing trouble.

What happens when you try to send a message? Does it appear to work but not? Does it produce an error message?
