Michael, I will re-add the owa. (SSL external FQDN) back to the validports for rpcproxy. But first I want to throw the monkey wrench into the pot. If I setup a local client to use RPC over HTTP and check the connection by running "outlook /rpcdiag" the client is able to connect to the exchange server without any problems using HTTPS. Which if I am correct suggests to me that its working on the inside but just not on the outside?? Andrew ________________________________ From: Michael B.
