my exchange 2010 server is up and running along side my exchange 2003. I've moved the OAB, Public Folders, etc and I'm ready to edit my firewall. When I point all my port 25 traffic to my new IP, i get an error (#530 5.7.1 Client was not authenticated ##). I'm thinking its becasue I still have my 2003 server up and the connector is routing all traffic thru that old server.
thoughts? will simply breaking the connector work? Or must I do more?
