Asynchronous Events

EWS Managed API

Topic Last Modified: 2006-06-11

Asynchronous events fire in response to a data request after Exchange processes the request.

There are two asynchronous events that fire in the Exchange store: OnSave and OnDelete.

Name When the event fires


When an item is saved to the store, after the changes are committed.


When an item is deleted from the store, after the deletion is committed.

The save and delete events also handle other events, such as moving or copying an item. Copying an item in a store generates a save event. A move causes both the save and delete events.
