I am running Server 2003 (SP2) with Exchange 2003 (SP2) and while my XP workstations with Office 2010 can RPC-HTTPS to the server for Outlook, my clients running Windows 7 & 8 – also running Office 2010 cannot. I have a SSL cert and https://owa.domain.com
works fine as do cell phones. I have tried the Microsoft Remote Connectivity Analyzer and it fails at - Attempting to ping the MAPI Mail Store endpoint with identity: server001.domain.com:6001.
I have validated all the proper port -80 and 443- and registry settings for 6001, 6002 & 6004. So, why does XP work but not 7 or 8?
