Windows Address Book - Outlook Integration

Outlook Integration

One of the undocumented features of the Windows Address Book is integration with Microsoft Office Outlook. A registry value has to be set at the following registry key location:

Note: Users should back up the registry before making changes.

HKCU\Software\Microsoft\WAB\WAB4

A DWORD value named "UseOutlook" (if not present already) can be created with its value set to 1. After setting this value, Outlook Contacts are shared with the Windows Address Book. This feature works only up to Windows XP and Outlook 2003. Windows Contacts introduced with Windows Vista does not support sharing contacts with Outlook. The above method works with any version of Outlook up to Outlook 2003, despite newer versions not including it as a configurable option in the user interface.
