If the OL client never spoke to the Exch server directly, it can't establish a connection. What Outlook version, OS / patch level, etc. on the client?

It failed and can't contact the exchange server? My SecureNAT client can successfully resolve public address. What is missing?

However, our exchange 2003 server is outsourcing to another company, and they refused to setup a ISA server on their end. Therefore, I tried to research a method to see if only one ISA server at remote end will be able access Exchange server with "RPC over HTTP" or not. How about this: SecureNAT client --> ISA server --> DSL --> Internet --> Firewall --> Exchange 2003 Please let me know.

Bets, anyone?

What if, SecureNAT client --> ISA server --> DSL --> Internet --> Exchange Is it possible? Please let me know.
