Exchange 2003 setup for Iphone 4

We are adding Iphones currently and are having trouble getting them to sync up with Exchange 2003 SP2.  OWA works fine for all users and we are not using SSL.   Port 80 is opened on the firewall as OWA works.   It says it can't connect to server on the iphone when trying to retrieve mail.  I have setup plenty of Iphones to access exchange servers but there seems to be an issue with this exchange server.  The error that I get is "the connection to the server failed".   I downloaded the active sync tester app for the iphone and passed all checks there.  

 I also tried the MS remote connectivity analyzer but can't seem to get past "SSL 443" errors even though it is set to "ignore SSL" when testing.

I have went through a few documents on the web to check the active sync virtual server in IIS and the exchange virtual server but no change.  Some of the things I checked were that forms based authentication was not checked, the domain was correct under directory security -> auth methos and also that SSL was not required.

I'm looking to try to get this resolved and if someone can explain the process or order of operations on the exchange server when making this connection.  


Thanks.

The last time I ran into this problem, it took me a couple of weeks to realize that the customer's Exchange 2003 server had not yet had SP2 installed.  Worth double checking the Exchange server version in System Manager.

Do you have any other devices currently working via Active Sync against this server?

I verified that it was SP2.   Also, this is the first time that we are hooking phones up via Active Sync.

Thanks.

netjgrnaut,   you are correct... i double checked the build # and it doesn't have SP2.  

Thanks again.

Glad that worked out for you.  Once I installed SP2, everything went perfectly.  Hope you have the same experience!
