Configuring the Online Directory

  • In the window which pops up click once on the ldap.whitman.edu account (This may be labeled differently depending on if you changed the label of the server earlier)
  • Click on the Properties button to the right
  • At the bottom of the General tab there is a box you can check for Check names against this server when sending mail. Leave this box unchecked.
  • At the top of the window click on the Advanced tab
  • In the field labeled Search Base type ou=People, dc=whitman, dc=edu. Those settings allow Outlook to search for the addresses of Students, Faculty, and Staff at Whitman.


  • Click the OK button

Using the Online Directory with Outlook Express

Begin composing a new message, type a last name in the To: field and click on the Check  button in the menu bar above the composition window.  Outlook Express will display a dialog asking you to pick from a list of everyone who shares that last name.  Once you select the person you want to send your E-mail to and click OK, Outlook Express will automatically enter that person's email address in the To: field.  You can also search for first names or partial E-mail addresses.
