POP/IMAP Not Sending over 587, Sends over 465?


  • We're finishing up our Exchange 2013 configuration. For the life of us, we cannot get IMAP/POP protocols configured in Outlook to send over 587. When I configure Outlook to send over SMTP 587, mail gets stuck in the outbox. MS Tech support had me try using 465 for SMTP and sure enough mail goes out.

    How can we get POP/IMAP to work sending over 587 for POP/IMAP protocols?
