Currently we have a department with a resource that is being used
pretty much for shared address books and nothing else.

I don't really want to move these address books to a specific user's
account as this dept seems to have fairly high turnover and I don't
want to keep having to move these from user to user.

Is there some better way we could be doing this to eliminate this
resource from our system and share the address books another way?
