If you are an escalation reviewer, you can close escalated items once you have finished work on them. A closed item is still visible to other escalation reviewers, but they can only perform actions on it after a department reviewer has reescalated the item.
To close an escalated item
In the Review pane, select one or more items that you want to close.
To select multiple adjacent items, click the first item, and then hold down the Shift key and click the last item. To select nonadjacent items, click the first item, and then hold down the Ctrl key and click additional items. To select all the items, press Ctrl+A.
