I want you to try to ping the FQDN of the Edge transport server from the HubTransportserver
Example from your hub transport server bring up a command prompt and ping EdgeTransportservername xxx.domain.com

If it fails you need to add the fully qualified domain name of the EdgeTransportserver to your DNS or

you can add the fqdn and ip  of the edgetransport server to the host file of your hub transport server

ref:  Finally got it to work. I had to go into c:\windows\system32\drivers\etc folder and open up the hosts file. In the hosts file I added the IP address and FQDN of my Edge Server. Then I was able to start the Edge Synchronization with no problems. After the Synchronization started I restarted the Microsoft Exchange Active Directory Topology Service, and made sure the Microsoft Exchange Edge Sync and Transport Service were restarted on the Hub Server, then restarted the Microsoft Exchange ADAM Service on the Edge Server, I also made sure the Microsoft Exchange Transport Service was started on the Edge. Everything now works wonderfully.

Thanks,

David Kellett

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why
