If you aren't using an LDAP, then remove it and add the Outlook Address Book
instead.
Go to Tools | E-mail accounts, select "View or change existing directories
or address books", and click OK. If you see an LDAP instead of the Outlook
Address Book, remove it. Then click the Back button, then select "Add a new
directory or address book", then "Additional Address Books", and add the
OAB. Then keep clicking Back until you get back to the first dialog box,
and go back to the Directories and Address Books list as you did earlier.
Once the OAB appears in the list, select it and then click Change to make
sure the Contacts folder(s) you want to display are listed. If any of them
aren't listed, you'll need to enable those Contacts folders as Outlook
Address Books by right clicking the folder, selecting Properties, clicking
the Outlook Address Book tab, and checking the "Show this folder as an
E-mail address book" box. Make sure you restart Outlook after making these
changes.
