The Deleted property returns a Boolean value that indicates whether an exception in the Exceptions table has been marked as deleted.

Read/write
The Deleted property applies only to recurring items that have been deleted. A deleted instance is an Exception item in the Exceptions table that has its Deleted property set to True.
For example, if a user creates a weekly recurring appointment, but during the third week of the appointment the user is scheduled to be on vacation, the user deletes the third instance of the appointment. Schedule+ places the deleted instance in the Exceptions table with its Deleted property set to True.
Applications can use this property to scan the Exceptions table for all instances of recurring appointments that users have deleted.
