ARCHIVED: In Mac OS or Mac OS X, how do I find someone's email address with Outlook Express 5 or Entourage?

Outlook Express 5+ and Entourage include a Directory Services feature that lets you query an LDAP server and find a person's email address based on his or her name. To make a Directory Services search, follow these instructions:

1. In Outlook Express, in the Folder List of the main window, click the blue arrow next to Directory Services so that the different LDAP servers are showing.

   In Entourage, from the Tools menu, select Directory Services. You should see several default servers listed (e.g., Bigfoot, Infospace, WhoWhere, Yahoo! People Search).

2. Click the LDAP server you want to search.
   
   
3. In the "Search for Name:" box, enter the name or part of the name of the person you are looking for.
   
   
4. Click the Find button.
   
   
5. The program will contact the service and list any matches. To send a message to one of the individuals in the search results, click his or her entry, then click the New Message To button. You may include the entry in your address book by clicking the button Add to Address Book. To find more information about the entry, double-click it.
