Gets or sets how many times the appointment occurs.
An integer value that specifies the number of occurrences.
If the IRecurrenceInfo.Range property is set to the RecurrenceRange.OccurrenceCount value, the OccurrenceCount property can be used together with the RecurrenceInfo.Start property to define the range of recurrence - the period of time in which the appointment occurs. In this case, the range of recurrence can be represented by the number of occurrences that should elapse until the recurrence is no longer in effect. The OccurrenceCount property specifies the number of occurrences.
