Modify a Recurring Appointment
Say you
created four occurrences of an appointment and the fourth Thursday
happens to be Thanksgiving, a holiday.
In this scenario, you would go to the fourth Thursday,
select the appointment and delete it.
What Do You See? If you modify or delete one
instance of a recurring appointment you will be prompted to confirm if
you want to Delete this occurrence (meaning just the one you
selected) or Delete the series (all of the appointments in the
series).
If you choose Delete this occurrence, the other
three appointments would remain in the calendar.
