Hello,
I'm in the middle of a migration from Exchange 2007 to 2010. I have one 2007 CAS/Hub/Mailbox server, one 2007 Edge Transport server and now one 2010 CAS/Hub/Mailbox server. I have created a test account on the 2010 server and I can send and receive messages internally. I can send a message from an outside domain (gmail) to the 2010 test account. However, I cannot send message to an outside domain from the 2010 test account. The messages are sitting in the queue of the 2010 CAS server which indicates to me there is a problem connecting to the Edge Transport. I have 3 send connectors and one of them is a smarhost. When I try to [PS] C:\>Start-EdgeSynchronization, the result is "CouldNotConnect". I'm at a loss as to what to try next. Any suggestions?
