The Microsoft Outlook Address Book is a container that includes the main Contacts folder and any others you add. It's used most often when you click the To button on an open message.
Outlook automatically makes the default Contacts folder available through the Address Book dialog, but you can also add other folders containing contacts to your address book.
Use the same procedure to remove Contact folders from your Outlook Address book, unchecking the option to use as an Outlook Address book.
Adding Other Contacts Folders
To add any folder containing Contact items to the Outlook Address Book:
- Right-click the folder, choose Properties from the pop-up menu, and switch to the Outlook Address Book tab.
- Check the box for Show this folder as an e-mail Address Book.
- You can enter a new Name of the address book to make it easier to distinguish from other Contacts folders. The name change affects only the address book display, not the actual name of the folder.
- Click OK.
Automatic name checking
You can configure Outlook to look for matching contacts when you tab out of the To, CC, or BCC field. This is commonly known as Resolve contacts. Rather than clicking the To button and choosing names, you can type people's names (or part of names) and Outlook will match them to existing contacts. If it finds more than one possible match, the name is underlined. Right-click on the name and choose the correct person.
If this is disabled, Outlook won't look for a matching address until you click the Send button or press Alt+K.
In Microsoft Outlook 2010 or Outlook 2013, to enable auto-resolve go to File, Options, Mail, Send messages section and select Automatic Name Checking.

The OAB behaves slightly differently in the two Outlook 98/2000 modes. In Internet Mail Only mode, it shows all contacts. In Corporate/Workgroup mode, it shows only those contacts with either resolved e-mail addresses or fax numbers. Newer versions of Outlook are all "corporate mode" and the Outlook Address Book works exactly the same in each.
