How do I edit or delete dates in a recurring appointment or available time series?

Go to the CALENDAR and click on any appointment within the respective recurring series. This will open that appointment and prompt you with five options: 

Edit Appointment | Edit Series | Mark as Missed | Mark as Cancelled | Delete

To edit only an individual appointment in the series, use the Edit Appointment button. To edit the whole series, use Edit Series.

The deletion options appear when using the DELETE button. You can delete an individual appointment in the series, the entire series, or only certain appointments in the series (custom delete).

The editing or deleting of available times series works in the same way: after you click on a block (instance) in the series and then select the option “View Available Time”, you are presented with similar options as in the case of appointment series.
