I am performing a Exchange 2003 SP2 transition to Exchange 2010. Exchange 2003's OS is Server 03 with SP2 (32Bit). Exchange 2010's OS is on Server 08 R2. We have three DC's on the network (two Server 08 R2 servers and one Server 03 with SP2). I have completed all the Active Directory prep for Exchange 2010, and have applied all the necessary hot fixes.
The Exchange 2010 SP1 environment has two servers. One holds the Hub Transport, CAS, Mailbox roles. The other holds the Edge Transport role. The transition seems to be working well.
I can migrate a mailbox to the new server without any issues. I can see the global catalog and everything appears to be working. The problem I am having is I can send mail fine, but am unable to receive. It was my understanding through my research that I can run both in parallel. Is this correct?
If that is correct than my guess would be that I have improperly setup the receive connector on the edge server? I did configure the EdgeSync Service, and everything appears fine on the Hub Transport server. Any help would be greatly appreciated.
Thanks!
