We develop a Java application, which retreives calendaritems from calendar folder of resource mailboxes through the Exchange Web Service protocol.
If we want to cancel a meeting we have to delete the calendaritem from the organizer's calendar.
How can we get the meeting's / owning calendar item's itemid (as I understand meeting is the calendaritem in the organizer's calendar) for the input parameter of the deleteitem method, if I have the resource calendar calendaritem's itemid only?
I could call finditem method on the organizer's calendar folder, but how can I determine whether the organizer's calendaritem is the meeting, which "owns" the resource's calendaritem?
