Cannot sync Calendar items from outlook to PDA

Question

Hi I am using Active sync via exchange to sync wirelessly. My devices are Palm Treo 750v's running Windows mobile 5 and 6.0. I am on New Zealands Vodafone Network
My problem is that we cannot sync from Outlook calendar to the PDA calendar, from the PDA to the calendar is fine when entered on the PDA.  We sync wirelessly via exchange 2003 on an SBS server.
I have have tried hard resets, different user accounts, different Treo 750v's, different versions of windows mobile all with no difference.  I have checked the firewall logs and event logs for errors. I have set all the virtual directories to the settings recommended by Microsoft. I ahve searched for a firmware update applicable to my devices without success
To me it seems like a permissions problem on a folder or virtual directory as when you sync an appointment from the PDA to Outlook you can modify it but the change is not reflected on the PDA although the PDA detects a change the appointment is not changed on the PDA.  If you move the appointment in Outlook to a new time that change is still not reflected on the PDA although it detects the change, but if you delete the message in outlook even though it is in a different time slot (in outlook) to the PDA copy it deletes the PDA copy when you synchronise.
Any ideas
Cheers Geoff

Hi,
The devices are syncing to exchange directly, we do not use active snyc on the desktop as we mainly run a terminal server / citrix enviroment.  The appointments show up in OWA and in Outlook when entered on the PDA (Treo) so this means they are getting to the server.  When entered via Outlook they show up in OWA but not on the PDA although the PDA will detect the change.
