organization’s contact list and restrict users from accessing the contact information of other organizations that also
subscribe to the Hosted BlackBerry services.
If your organization permits customers to have limited access or read-only access to the Microsoft Active Directory, you can
configure the BlackBerry Enterprise Server to use MAPI, LDAP, or both to retrieve recipients’ email addresses. If your
organization permits customers to have full control of subtrees in Microsoft Active Directory and you configured Microsoft
Active Directory for multi-tenancy, you can configure the BlackBerry Enterprise Server to limit the scope of the LDAP
search.
To configure Hosted BlackBerry services, you must use a licensing model for the BlackBerry Enterprise Server that is
specific for Hosted BlackBerry services.
For more information about Hosted BlackBerry services, see the BlackBerry Enterprise Server Planning Guide.

If you configure Hosted BlackBerry services, you must make sure that the name of the organization that each BlackBerry
device user belongs to is listed accurately and consistently in the entry for each user in Microsoft Active Directory. For
example, if the organization’s name appears as an acronym in some entries but in expanded form in others, the BlackBerry
Enterprise Server might return inaccurate search results. If a user tries to search for another user's contact information but
you did not specify the name of the organization that the other user belongs to in Microsoft Active Directory, the BlackBerry
Enterprise Server does not return any search results.
You can specify the organization name in the entry for each user in an LDAP field such as the Company Name field. If you
specify the organization’s name in a field other than the Company Name field, you must specify the name of the LDAP field
when you configure Hosted BlackBerry services. If you do not specify an LDAP field, the BlackBerry Enterprise Server uses
the Company Name field to search for contact information.
