Configuring LDAP directory search in Outlook 2003/2007

Configure LDAP directory search in Outlook 2003/2007 so you can search for all people at Illinois State University.

By default, Outlook on Exchange uses the Global Address List (GAL) for people searches. The GAL includes only Exchange users, which means a majority of people on campus are excluded from the search.

Configure the LDAP directory search in Outlook 2003 or Outlook 2007 to search Active Directory (ad.ilstu.edu). This allows you to search everyone at Illinois State University, not just Exchange users.

Configure "ISU People Search"

To configure LDAP directory search in Outlook 2003/2007, do the following:

  1. Open Outlook.
  2. Do one of the following:
    • In Outlook 2003, click Tools > E-mail Accounts.... Select Add a new directory or address book and click Next.
    • In Outlook 2007, click Tools > Account Settings.... Click Address Books and then click New.
  3. Select Internet Directory Search (LDAP) and click Next.
  4. In the Server Name: box, type ad.ilstu.edu.
  5. Click the check box labeled, This server requires me to log on.
  6. Leave the User Name: and Password: boxes empty (unless you are setting this up at home; more information for home users is found below).
  7. Click the check box labeled, Require Secure Password Authentication (SPA).
  8. Click More Settings....
  9. A message appears which says, "The E-mail Account you just added will not start until you choose Exit from the File menu, and then restart Microsoft Office Outlook." Click OK.
  10. Under Display Name, delete ad.ilstu.edu and type ISU People Search.
  11. In Outlook 2007, click the Search tab. Then click the check box labeled, Enable Browsing (requires server support). (This option is unavailable in Outlook 2003.)
  12. Click OK.
  13. Click Next.
  14. Click Finish.
  15. Before using LDAP Directory Search, close and reopen Outlook.
