Configuring automatic address completion in Mail for Mac OS X

You can configure Mail for Mac OS X to automatically complete e-mail addresses when you are composing a message. This is similar to the default behavior in Microsoft Outlook.

For example, you could start typing "Joh" and Mail would show you a list of all the users on campus with the first name John.

Example, typing "Truman" shows all addresses with Truman in the name:
Composing a message
To configure this feature in Mail, follow the following steps:

  1. Start Mail and enter the Mail Preferences by clicking the Mail menu and selecting Preferences
  2. Click on the Composing tab at the top of the window and then check the "Automatically complete addresses" box. Next, click the "Configure LDAP" button.
  3. Click the + button in the bottom left corner
  4.  Fill in the Server Info window as show. Enter your e-mail address as the user name and your password. Note: If you change your password in the future, you will need to reenter it here for address completion to continue to work.
  5. Click "Save" then "Done" and exit the Mail preferences.  Try composing a new message and enter "Truman" in the To: field. Pause a second and Mail should suggest several addresses. This will confirm that address auto completion is working.
