I'm having a bit of an odd problem: Exchange 2003 (SP1). When the user connects to it via Outlook 2003, the server reverts the Directory connection type to TCP/IP. But, the Mail connection type is HTTPS. This leads me to believe that the RPCProxy is working as I can do an rpcping with no problems. Any ideas? Tony --------------------------------- Do you Yahoo!?
