external exchange domain through edge transport server
Posted on 2015-02-13
I have the following setup.
Exchange 2003 on domain2.com (external)
Exchange 2013 on domain1.com
In the exchange 2013 setup there is an Edge transport server and the plan is to have all mail go through that for both domains. I have send / receive connectors setup on 2013 exchange servers to allow domain2 to email through domain1 and out the edge transport service.
Currently I have no problems emailing back and forth between domain1 and domain2. I can also send email outside both domains from domain2 and domain1 through the edge transport server.
My issue is with inbound email from the outside to domain2. I can send to domain1 from the outside with no issues. On the edge transport server I see the emails for domain2 in the message tracking logs making it into the server, but can't tell where they are getting hung up. I did get a few non deliverables a few hours later from the edge transport server.
Not sure if the issue is with the edge transport server or if there is a way to see where it is hanging up.
