We have a shared address book in our dept, where we all have read/write
access to it.

Co-worker tried to modify an entry and was denied. He went into the
account that shares the book, deleted him in the sharing option, and
added himself back.

He can now edit entries in this book, but now he does not have any of
our shared address books listed when he goes into the address book. He
needs to go into frequent contacts to find the shared address books.
