ISA Server 2004 blocks Exchange Active Synch Traffic

I have a SBS 2003 Premium Server and tried to setup iphone active synch. I have OWA and RWW (Godaddy SSL) working for some time with no problems. I'm unable to get the iPhone to synch with Exchange.
I turned on logging in ISA and I can see that ISA is blocking the traffic from the iPhone. I was under the impression that the OWA rule would cover the OMA traffic.  Can anybody give me some advise on this. Below is the log from ISA Server

Try recreating the OWA/ OMA rule within ISA server, carry out a backup first. The documents listed by MinoDC detail what to do with the rules. Also see the following for details on what to carry out when recreating/ creating the OWA/OMA rules http://www.petri.co.il/publishing_owa_with_isa2004.htm
