iPhone and ActiveSync Issues

I am in the process of setting up ActiveSync for the iPhone.
We have an Exchange 2003 sp2 backend server and an ISA 2004 server.  The ISA server sits in the DMZ - so far I have ensured that ActiveSync is enabled and setup a web listener on the ISA (essentially it is acting as the exchange frontend)

Connections between the Iphone and ISA server on port 443 are allowed.
Connections between the ISA and Exchange server on port 443, and 80 are allowed.

I have tried to test the connection using https://www.testexchangeconnectivity.com/
But it reaches the SSL validity and fails (despite checking to ignore) - I have temporarily setup a CA in the domain and am now trying to figure out which server to setup teh cert for and have made various 'unsuccessful' attempts

Oh, we don't have OWA setup so if there is anyone who has been in the same situation ad maanged to get this working I would appreciate some advice

Hello Shepweed,
Take a look at Apples documents for this.

Hi, I've looked at both - but still getting nowhere.

You said you dont have OWA setup, but do you have Outlook Mobile Access enabled? If not that could be your problem.

There is no plan to enable OWA - but I used OMA as a test as it was suggested on various forums.  Like I say, this only appears to work internally anyway.  Any suggestions?
