I have a new Exchange 2010 server that I am trying to connect to via active sync. Presently I am still using my old Exchange 2003 server for this with out any trouble. When I go into my firewall and point port 80 to the new Exchange IP Address I get a cannot connect to server error. As soon as I switch back to the old server I can with out any issues. Outlook Web access does work when I make the IP switch for port 80 on the new server.
Thoughts? The error says cannot connect to server.
