Cancel an Event
Event owners can cancel events at any point before the event start date. If candidates have already registered for an event that you then cancel, their Registered status remains, but they'll receive a cancelation email.
Candidates will see a Canceled label on the event in their candidate self-service. New candidates can't be added to canceled events. If an event is posted, and you cancel it, the event is automatically unposted. All event URLs associated with a canceled event become unavailable.
