I have been running OWA and Outlook RPC over HTTPS successfully in a Win2K3/Exchange Srvr 2003 environment, but recently my ISP blocked Port 443, so now I can only get in via VPN.
Is there a way to change the SSL port to something other than 443? If so, can someone point me to the relevant documentation? I assume I need to change both IIS and Exchange Server, and of course the Outlook RPC over HTTPS config and OWA URL. I think I can handle the last two but could use some help getting started on the first two - as well as knowing what else I might need to change.
