I have set up rpc over http on a single Exchange server sp1 according to MS in their KB but I cannot get it to work properly for some reason. I cant get Outlook to find our mail server over http and I think it might be a firewall issue. What ports do I have to open up if any on our external firewall other than 80?
If Anyone else has suggestions on what I am missing or done wrong, please let me know.
This server is an Exchange 2003 server with server

Thank You

This is a common stumbling point. What you are missing is that exchange really uses rpc over httpS. Therefore port 80 is not involved; the port you need to open is 443 for SSL.
Good luck :-)
