When I create an exception appointment, should the regularly scheduled appointment still be shown? For example I have rec appointments that occur on Fridays at 11AM. When I drag and drop one of the occurrences to a brand new day and time (Wednesday for example) the new appointment shows up but the old one on Friday also is showing up. When I drag-and-drop in the RecurrenceExceptionCreated event I create a new exception and update master appointment's recurrence rule with the new rule containing date and time of the exception. In the new exception appointment I reference DataRecurrenceParentKeyField of the master appointment. Since the regularly scheduled appointment is modified I don't want to display it any longer for that week. What am I doing wrong? Thanks
