Personal address books

Hallo,

We are in the process of rebuilding our domain and exchanging all our
computers on the lan with new ones. In this process I have descovered
that alot of our users have started useing personal address book and
placing the *.pab file locally on their computers. This is giving me
some headace because they have not used outlook contact as the source
file for the addressbook, but put the addresses directly into the
addressbook. So if I export their mailaccounts to a *.pst file (on the
exchange server), this mailaddresses will not be a part of this *.pst
file. So, anyone have a solution to this problem? Is there anything I
can use to find out who is useing the addressbook, where the
addressbook is located on the computer and how to move it??

Thank's in advance.

B'regards J
