Does a customer want to cancel their weekly or recurring (repeating) appointment?
This can be done quickly in the calendar.
1. Calendar
2. Double-click the appointment
3. Delete
4. Check the box "Delete future appointments"
5. Click on "Remove"
Now the entire string from the appointments you double clicked will be deleted.
Note: If you only need to remove a few appointments from the series of appointments, you should not select the check box "remove future appointments".
