OL98: If Appointment Is Dragged from a Public Folder to a Personal Calendar Folder Synchronizing Stops

• Microsoft Outlook 98

SYMPTOMS

If you develop a custom calendaring application that uses public folders to hold the appointments, users can drag appointments from the public folder to their personal Calendar folder. If the appointment is created via a custom form and the form has custom properties, dragging the appointment from the public folder to the personal Calendar folder may stop Outlook from synchronizing with the user's personal Calendar folder on the Microsoft Exchange Server.

CAUSE

Data from custom fields on custom forms are stored in named properties. When an appointment was dragged from the public folder to the user's personal calendar, it is initially put into the calendar cache in the Offline folders (OST). Periodically, the OST will synchronize with the calendar on the user's Exchange Server.

There was a logic error in Outlook that caused a named property to be incorrectly added to the property set on the private folder information store. When Outlook tried to synchronize the Calendar folder, it would try to map the ID of the named property to a name. Since the named property was incorrectly added, Outlook could not map it, and synchronizing stopped.
