One year ago, the company I work for moved to Office365 and I immediately lost access to my emails over POP3.
After finding that OAuth2 was required, I tested the Thunderbird email client and it worked, but then I knew it was necessary to use IMAP instead of POP3.
So I just converted my account in Seamonkey to IMAP, selected OAuth2 for authentication and since then it has been working perfectly.
