    receiving a request at a first mailbox server in the first forest to access PIM data for the second user in the second forest;

    in response to the first mailbox server not locating the PIM data for the second user, providing from the second directory server in the second forest identification information for a mailbox of the second user to a PIM application residing in the first forest in response to a request received from the PIM application in the first forest; and
