Configure the Address Book for LDAP

Lightweight Directory Access Protocol (LDAP), also referred to as Internet directory services, is used to find e-mail addresses that are not in a local Outlook address book or a corporate-wide directory such as the Global Address List. LDAP queries directories on other servers to look up names and other information that can then be viewed in Outlook.

The LDAP service requires a network connection to the LDAP server. Microsoft Exchange supports LDAP, or you can locate an LDAP server on the Internet, on your organization's intranet, or through another company that hosts an LDAP server.

To configure your Address Book for LDAP, you will need the name and port number of the LDAP server.

Set up and configure an LDAP service

  1. On the Tools menu, click Account Settings.

  2. On the Address Books tab, click New.

  3. Click the Internet Directory Service (LDAP) option, and then click Next.

  4. In the Server Name box, type the name of the server that was provided by your Internet service provider (ISP) or system administrator.

  5. If the server that you specified is password-protected, select the This server requires me to log on check box, and then type your user name and password.

  6. Click More Settings.

  7. Under Display Name, type the name for the LDAP address book that you want to be displayed in the Address Book list in the Address Book dialog box.

  8. Under Connection Details, type the port number of the LDAP server provided by your Internet service provider or system administrator.

  9. Click the Search tab, and then change the server settings as needed.

    The search time-out setting specifies the number of seconds that Outlook spends searching the LDAP directory to resolve names in a message. You can also limit the number of names listed in the Address Book that are returned from a successful search.

  10. On the Search tab, under Search Base, if the Custom box is not filled in, type the distinguished names that were provided by your administrator.

  11. Click OK, click Next, and then click Finish.
