iPhone, Exchange 2003, OWA, ISA 2006

I just got done setting up OWA with ISA 2006 for iPhone test users. One thing that I ran into, which I have seen in the past, is an issue when you have an ISA server with only one leg, purely in the DMZ.

With OWA if you don't want users to have to type in /Exchange when connecting to the Exchange server you have to basically create a redirect rule that comes into effect when a user just types in the root of the OWA server. That rule then forwards them to /Exchange. Simple, but a PIA if you are trying to figure it out.

Here is how to do it: http://www.messagingtalk.org/exchange-2007-owa-url-redirection-using-isa-2006
