A PAB is an option with the version of Outlook I am using.

I went through the steps to add an addition data file and selected
address file. PAB is listed in the options. So I selected this and was
able to add a single entry to the PAB. I was also able to verify that
multiple users can access the PAB.

The problem I am facing is how to transfer the 1000+ entries transfered
from a contact folder into CSV file, into a PAB.
