A Microsoft Exchange Server 2007 user updates a meeting request by using Exchange ActiveSync on a mobile device. However, later updates do not match the calendar item that the user updates by using Exchange ActiveSync. Therefore, the original meeting request is not removed from the recipients’ calendars. Additionally, later updates create new meeting requests in the recipients’ calendars. For example, consider the following scenario:
When you send an updated meeting request by using Exchange ActiveSync on a mobile device, the request does not include the PR_OWNER_APPT_ID property. Then, Exchange Server 2007 sets a value for the PR_OWNER_APPT_ID property that does not exist. This value does not match the original calendar item. Therefore, you experience the problem problem that is described in the "Symptoms" section.
