Im standing up an Enterprise Exchange 2007 system and Im currently getting no mail flow between the mailbox servers and the hub transport. Here is the error that keeps coming up
Event Type: Warning

The Microsoft Exchange Mail Submission service is currently unable to contact any Hub Transport servers in the local Active Directory site. The servers may be too busy to accept new connections at this time.

Ive tried the solutions listed in the website but it has not corrected the issue. Let me give you a little background
I currently have an Exch2003 Enterprise setup in domain ABC.com. We are currently deploying another separate forest, which Ill call domain XYZ.com. Both domains are connected by a two-way trust and there are not child domains in either domain.
I built an Edge, and Hub transport server. The Edge is in the DMZ as a standalone server and not part of the XYZ domain. The Hub and mailbox servers are behind the DMZ and are a part of the XYZ domain. The Exch2007 system is on a different subnet than the DCs.
Im able to set up a connector from domain ABC (Exch2003) to XYZ (Exch2007). Ive sent test messages and they were received by the Edge and Hub transport but never made it to the mailbox server.
Any help would be appreciated.
