Create .csv file type for fax service

Hello,
We have Outlook 2003 clients on a LAN with a Small Business Server 2003
Standard editon box. We require a single fax document sent to all new or
existing clients simultaneously with our new Microsoft Shared fax service
from SBS 2003. Is there a way to create a .CSV file type format in Microsoft
Excel for our new client database and import this information into Exchange
as a seperate address book for central use for faxing purpose? Thank you in
advance for your assistance.

Joe
