I am trying to get RPC over HTTP working with Microsoft Exchange 2003. When I connect from the LAN (using the Exchange Server's public address) it works fine. As soon as I leave the public network, I get the following error:
"The Exchange server is unavailable."
I am running my own Certificate Authority, and requiring SSL to the server. I have installed the certificate in the "Trusted Certificate Authorities" store, and no longer get the certificate warning when browsing to OWA.
Any help greatly appreciated.
