You can assign permissions on Address Book views for Microsoft Windows NT accounts. For information on permissions, see Microsoft Exchange Server Getting Started.
You can use search control restrictions on the Permissions property page to control which Address Book views users see. For example, if you are hosting multiple companies on a single Microsoft Exchange Server, you can prevent users of one company from viewing the Address Book views of another company. You do this by creating a Windows NT group for each company you are hosting and setting the Search role for each Windows NT group.
Note After a mailbox is created, you must add the Windows NT user account associated with the mailbox to the Windows NT group associated with the Address Book View container.

When remote users connect to the Microsoft Exchange Server computer, they can download offline Address Books to their laptops or portable computers to get information about other users in the organization. You can restrict the offline Address Books that a user can download by imposing search control restrictions on the Address Book View container.
Note Users can download only the offline Address Book that they are a member of; they can't download any other offline Address Book View containers.
