Do you have this Registry key on either machine?...

HKEY_CURRENT_USER
\Software
\Microsoft
\WAB
\WAB4

If not, STOP; If so, is there a DWORD named UseOutlook in the right-hand
pane and is its value set to 1 (one)?

If not, STOP; If so, Address Book is configured to share contacts with
Outlook, even if you don't use it (can happen with the install of Office).

Please reply to *this* thread with your findings.

(maybe Outlook, but not intentionally or used) installed on which I want
the same address book.
