We are transitioning from Exchange 2007 to 2010. We have 1 AD domain and 4 AD sites. Each site has Exchange installed. The larger sites have the roles separated, with the smaller sites combining CAS and Hub. I have one small site that Outlook Anywhere does not work from outside of the network. I have confirmed that OA works inside, as well as TCP working both inside and out (via VPN).
I have checked the log files and cannot find any problems. I have tried disabling OA, uninstalling RPC-Proxy, removing IIS directories, reboot, etc etc several times. It didn't help. I have been all over testexchangeconnectivity.com. It reports that OA can connect fine.
I'm not sure what to do next. Maybe I'm looking at the wrong thing? Not CAS? I can move mailboxes from this site to other sites and connect just fine. Not sure what to do.
Thanks in Advance-
