Identified
The Exchange Messaging team is investigating mail delivery issues to Live, MSN, Outlook.com, and Hotmail email addresses. We believe this is due to compromised accounts sending mail that resulted in the blacklist of a few of our outbound IronPort appliances. The Messaging team has implemented a temporary workaround as these blacklists are corrected. If you continue to see mail delivery issues to these domains, please contact Tech Support at 573-882-5000.
