You can easily archive events you are no longer using. This effectively hides the event from all students but allows you to make it active again at a later date.
Navigation
In the left navigation, make sure you are in the Academy Workspace.
When in the Academy Workspace, select Training Admin for all Training Administration options.
Select Manage Training and then select In-Class Events.
If you're looking for a Virtual Event instead, select that option.
Archiving an Event
In the Event Management space, on the right, select Archive.
Please note that when it comes to bundle events, if you cancel or archive the master event then all the other offers will be cancelled or archived as well.
Archived events can be found by filtering the list of events by Archived status.
