Routing emails to internet directly from Hub Transport Server

Are you sending from a client like outlook or from web access. If you could try from both and report results.

Does the send connector have as address space " * "? Is it sending out through smarthost or DNS? Any external firewalls on the network?

Hi, I get the same error message from both outlook and owa. We checked the firewall logs and nothing is leaving our hub transport server destined for message labs.

Cheers, Dylan.

The address space is set to " * " and we are using a smarthost  and I've used nslookup to check I can resolve the name. I have actually had external mail working using an edge transport server, but seeing as we are behind a firewall and are using messagelabs for anti-virus and spam we removed the edge transport server.Basically I disabled the edge-sync connectors and recreate 2 send connectors, this worked for sending and receiving external mail, so I removed the edge subscription and deleted the 2 edge sync connectors and since then it hasn't worked. Could there be something left over from edge-sync causing it to fail?

Cheers, Dylan.

this command will completly remove the Edge Sub;
Remove-EdgeSubscription -Identity EdgeServerName -DomainController dc.domain.local
Also make sure there are no SMTP connectors still pointing at the edge server as the edge sub is only half the config, there will actually be an SMTP connetor that used to deliver to the edge server and recive from.

I've run the remove-edgesubscription command, but it comes back saying that the object cannot be found on the domain controller, can I use adsiedit to remove the object?

Cheers, Dylan.

These are the only 2 send connectors I have setup

Cheers  Dylan,

The command should be run in the exchange power shell. On a server with exchange installed on it.
Do you still have 2 Send connectors configured? You only need one now you have no edge server.

Brilliant, that's worked! I was under the impression we needed 2 send connectors. I've been pulling my hair out over this one for a couple of days! thanks for your help jfletchster.

Cheers, Dylan.
