Returns or sets whether to include Recurrences in a collection sorted on the Start property in ascending order.
If TRUE, recurring Appointments are expanded to all dates on which they occur.
If FALSE (the default), recurring Appointments are only associated with the first day they occur.
Set this property TRUE if you want to find all Appointments that fall on a specific date.
If IncludeRecurrences is set, you could potentially have a collection with an infinite number of items (if you have any recurring Appointments with no end date).
Because of this, you could get into an infinite loop if you are not careful.
