I am also experiencing the same problem. I used the CIW to create a mst file
from which I have creeated a Office 2003 GPO install. Within the mst I
selected to add in an Outlook Address Book.

The GPO deploys and installs Office 2003 but it does not add the Outlook
Address Book to the profile. I can add this in manually afterwards but I do
not understand why the MST file is not working.

Have you any suggestions? Thanks for any help that you can offer.
