In Mac OS X, how do I search for an address in the ADS Global Address List?

In Mac OS X, you can connect to Indiana University's Exchange server with Address Book. Once connected, applications that use Address Book's data (e.g., Mac OS X Mail) can look up names and email addresses in the Global Address List (GAL). You can also search directly from the Address Book.
Note: UITS has not tested these instructions with previous versions of Mac OS X, and recommends that you upgrade to Mac OS X 10.5 or later.

Address Book configuration

Mac OS X 10.7 (Lion) and 10.6 (Snow Leopard)

Note: You can only use the Address Book to search the Global Address List in Snow Leopard and Lion if you have a Microsoft Exchange account.

1. Open Address Book, normally located in your Applications folder.
   
2. From the Address Book menu, select Preferences... .
   
3. At the top of the resulting window, click the Accounts tab.
   
4. Click the + (plus sign) to add a new account. In the sheet that drops down, configure the settings as follows:
