We are currently working on an exchange migration project, migrating data from an older groupware solution to Exchange.
The problem we are having occurs when importing calendar-objects into different calendars.
Imagine that a meeting has an organizer and 3 attendees; the iCal for the meeting is imported into all four calendars. Custom MAPI properties are set on the objects:
- Flags are set to organized in the organizer's calendar, received in the attendee's calendar
- PidLidGlobalObjectId and PidLidCleanGlobalObjectId are set to identical values for all instances
- If attendees attempt to accept or decline the meeting the organizers calendar is not updated.
- If the organizer updates the objects this appears as a duplicate ( the duplicate is linked to the organizer's calendar) in the attendee's calendars
Does anyone know what else might be required to solve this?
