Account owners and their team members have different permissions when it comes to archiving and deleting things in Ahsuite.
Any team member can archive or un-archive a task, file, work journal, or password. Only the account owner can archive a client or delete anything except a client.
To view archived items, click the filter icon and select "show archived".
The account owner can delete items that have been archived. An item must first be archived before it can be deleted.
