Continuing the blogcast series on infrastructure essentials.

With our new rule in place on the ISA Server, this sixth part of configuring TPC over HTTP for Outlook 2003 first takes a quick look at the effects on Outlook Web Access - we now get a basic authentication challenge instead of Forms Basic Authentication. However, we can still log on. We'll come back to that in a few parts time.

Our Outlook profile still has the internal name of our Exchange Server configured for the Exchange Proxy Server, so we alter that to point to the external name, mail.contoso.com. On restarting Outlook with the rpcdiag switch, we see that it connects using RPC over HTTPS through our ISA Server correctly from the Internet. Result!

We put our Outlook profile back to a more "normal" RPC/HTTPS configuration by connecting using TCP/IP on fast networks first, and HTTPS on slow networks first. We then take a look at what happens when we switch our client from internal to external to internal networks. Perfect!
