Save several clicks by closing tickets that are duplicates or spam from the list view; you can even do it en masse.
Click the three-bar "hamburger" menu in the top left of your case. Click "Mark as Duplicate" or "Mark as Spam."
This functionality will only work from a list view such as Case → Open Cases (My Groups). It can't be used from a dashboard.
If you still have questions or need additional assistance, please submit a ticket or call the ITS Service Desk at (858) 246-4357.
