Synchronous Event Methods
Microsoft® Exchange provides synchronous event notifications by calling the IExStoreSyncEvents Interface methods in the following table.
|OnSyncSave Method||Called before an item is saved to the Exchange store.|
|OnSyncDelete Method||Called before an item is deleted from the Exchange store.|
While it runs, the synchronous event sink has exclusive control over the store item that triggered the event. No other process or request can access the item until all event sinks have finished running.
To set the order in which synchronous events are processed, see Event Notification Priority.
