I have an HP iPac hx2795 pocket pc.
Windows Mobile 5.5 OS 5.1.1702 b 14366.1.0.1
Laptop is running has Win XP SP3 with office and windows updates thru today.

Whenever I create an appointment on the ipac and then run activesync, my PC
version of Outlook will not update the Calendar if "Use Cached Exchange Mode"
is selected.

When I de-select the "Use Cached Exchange Mode", the appointment is now
visible.
I have tried to delete the OST file and restart the application with no
success.

When I open this users calendar via the "Open a shared calendar" from
another laptop or PC the appointment is visible.

I have been searching for a few days on a solution, with no luck.
Any help on this is much appreciated.
