How to delete a scheduled appointment

Go to the appointment you wish to delete and put it in edit mode. Hover over the Change Status and select "Cancelled". 

Once cancelled, go back to the Case File -> Records and click on the newly cancelled appointment. 

Once you're back in the appointment view, click on the Delete button. A pop-up will then appear asking if you want to delete the document, click Ok. 

Once deleted, the appointment will be removed from your calendar.
