I am working on the migration of exchange 2003 to exchange 2010, so far the 2010 is up and running, I move a test mailbox to 2010, and internal email works from 2010 to 2003, no problem, i can send emails from 2010 to the outside, my problem is receiving emails from the outside to the user on the 2010 box, we have a 3rd party service for spam filter, all inbound and outbound is managed and controlled by the service, I dont know what I am missing, why I cant get external emails to the users on the 2010 box....
Any ideas? I have been playing the the receive connectors, but still can figure this one out!
Thanks!!
