When a single occurrence of the recurrence appointment is edited, recurrenceID field will be added which holds the id value of its parent recurrence appointment. It is applicable only for the edited occurrence appointments. Therefore the collection passing to the saveEvent with action as EditOccurrence should have RecurrenceID field as shown above.
