Can I restrict other people from making changes to my address books?

If you are the owner, or an admin, of an address book, you can change permissions for any other team member. You can select permissions (read only, read/write or admin) when you add a new team member or edit existing permissions in the team member’s settings.

To edit existing permissions, select “Team members” from within your selected address book.

Change the permissions below the team member’s name and click “Save permissions”.
