+			
+			This function notifies the observer of an add/change/delete/move of a mailbox object.
+			The observer will not be notified of modifications that are performed from the observer's
+			own message store session.
+			
+			When adding a message, no observer notifications will be sent for the message, or for any
+			attachments, until the message is committed (for the message itself, or for any attachments).
+			When the message is committed, an Add notification will be sent for the message but not for
+			any of the attachments.
+			
+			When deleting a message or a folder, a Delete notification will be sent for the top-level
+			deleted object, but not for any subordinate folders, messages, or attachments.
+			
+			When copying a message, an Add notification will be sent when the copied message and all
+			attachments have been fully committed, but no notifications will be sent for the attachments.
+			
+			\param aFlags:   This parameter will hold the value of the flags property for the modified
+			                 object.  The value will be KMsgStoreFlagsNotFound if the flags property is
+			                 not found in the modified object and for operations that only update the
+			                 content of the object.
+			
+			\param aOtherId: This parameter will be the new parent ID for move operations,
+			                 otherwise this ID will be the parent of the aParentId container.
