Hi Tom, That's a pretty interesting question. Have you enabled all RPC outbound to the user's Exchange Server? I'm assuming that you're talking about Outlook MAPI connections.

I setup guest Internet access for him today, but the mail servers cannot be accessed through our ISA 2004 server. I tried to Telnet with no luck. Now with my desktop PC that is part of my domain, I have no trouble. I have the Firewall Client installed. I tried to install the FW Client on the guest PC, but it still did not work. If the guest is able to connect to the Internet, shouldn't we be able to telnet to the mail server? I just upgraded to ISA 2004 yesterday, so I'm sure something is not set right, but am not sure what it could be, because I am allowing all protocols access at this point. Any advice?
