To remove someone from a case team or unassigned binder:
1) Open the sharing menu for the case or unassigned binder.
2) Uncheck the box next to the person you want removed and then click "Update." Note: If the person is an admin, uncheck the "Make admin" box too.
Note: If you don't see the person you want removed from the case or binder, it may be because you've already removed them from your Contacts list. If so, add them back to your Contacts list and then follow the steps above to remove their access to your case or binder.
