This article shows how to see what changes were made to an appointment after it has been cancelled, deleted, or moved to another date, using the Trail feature.
Go to your Appointments calendar and navigate to the date when the appointment previously existed.
Double-click on a blank space in any staff column as if you were going to book an appointment.
