451 Temporary local problem - please try later - Exchange 2010


  • I have a message sitting in the queue that is failing to go out with this message. My research suggests it is a DNS problem, but I don't understand what I'm reading well enough to make a fix. This installation of Exchange 2010 is recent, we migrated from hosted mail about 2 months ago. The issue is not happening to all users, if that helps.

    I'm looking for guidance on troubleshooting steps, bearing in mind I'm pretty new to Exchange.
