Entry Identifier Identifies Specific Object for Notification

An application can register to receive notification of the deletion of an object in any of three ways:

• In the call to Advise, pass the entry identifier of the particular object, whether it is a folder object or a message object. To receive notification of the deletion of a message within a folder, the application must be registered for notifications about the message itself, not the folder that contains it.
• Pass NULL in the Advise call to request notification of all deleted objects in the information store.
• Register for table notification on a contents table of the folder.
