When you update All instances of a repeating event, the entire series of appointments is deleted and then re-created, using the start date of the instance being edited. For example, if you update a repeating appointment using the third instance of a series that has five instances, the first two instances are deleted and the third instance becomes the first instance with four instances following it.
If you want to maintain a series of repeating events with their original dates, either edit the first instance of the series, or edit any other instance and change the start date to the new date (e.g. the date when the first instance occurs).
This applies only when you change the following event details: location, calendar, date, time, or repeat details. Changing other appointment details (e.g. description, duration, or summary) does not cause the series to be re-created.
Removing the repetition details of a repeating appointment
Uncheck the Repeat check box to erase the repetition details and make the appointment non-repeating.
