Scenario -

in my program i want to sync appointments between my pocket pc and laptop.

Issue -

AppointmentItem object model of Outlook 11 (reference
-Microsoft.Office.Interop.Outlook.AppointmentItem) has different object
model than the one Windows Mobile 5.0 Pocket PC SDK (reference
-Microsoft.WindowsMobile.PocketOutlook.Appointment)

Some key properties such as creationtime, modificationtime, etc are missing.

When we create the custom properties for the missing fields (using
Properties collection of Appointment class) and do the activesync, the custom
properties (ItemProperties or UserProperties collection) are not
reflected/synced on the PC (outlook 11).

Question -

Can someone guide us on how to transmit custom properties for appointment
object between pocketoutlook and normal outlook?

BTW where is "lastmodifiedtime" for each appoitment item stored for each
pocket outlook calendar? When syncing between outlook and pocket how does
active sync figure out the latest version. The revision must be stored
somewhere?

I checked repl.dat and found nothing useful. Can someone help
