Enigma99 is right. But if you didn't have Exchange server or an email server with a distribution list, you can create a fax mailbox that's assigned the shared fax number. This is your group mailbox. Then make a new fax group and make these user's fax mailboxes members of that group. In the group mailbox, using EFM admin util, set Auto Receive 's Automatic Forwarding to use "Network Recipient" and type the group name in the User field. Now, a fax received by the group mailbox, copies everyone belonging to that group.
