is used only if you have an exception appointment since this appointment needs to be referred to the master appointment. The exception appointment is stored in the data base just like any other appointment but it has RecurrenceParentID
value. If you reset the master appointment's exceptions all exception appointments from the data base will be removed and the master appointment's recurrence rule will be modified as well.
Please find more information about Working with Recurring Appointment.
@Tony As I mentioned earlier the RecurrenceParentID is used only in cases of recurrence appointments. Could you please explain a bit more about your scenario and the specific case?
