Hi guys.
Frontend - Exchange 2013 CU10
ExchangeEDGE 2013 - CU11
We see messages in queue on Exchange 2013 edge server with 451 4.4.0 error and can not figure it out why they dont go thru
We have tried solving it going on Exchange 2013 FRONTEND under send connectors.
We have choosen there send connector EDGESYNC - from SITE to INTERNET and marking: Use the External DNS lookup settings on the transport server.
And restarting transport service on Exchange2013, but the problem remains the same.
Please help
