    And I just got off a support chat with Microsoft for approx 1 hour and they tried everything. They suggested I get back with Cox.

      I finally figured this out. I disabled/turned OFF the McAfee VPN option and now I am able to send emails!

      Just guessing here but the VPN option must have been changing my IP address and Cox was thinking this was a blacklisted IP???

      Not sure of the technical details but everything is working again!
