Internet EMail - Changing Email Type in Properties

[Madigan]

I'm trying to find out if it's possible to change the default settings
for E-Mail Type from SMTP to FAX. Right now if I click on a contact's
email address the properties for that EMail Contact open and SMTP is
listed as the default Email Type. For a special project we have I
need some user's set to Fax rather than SMTP.

I do not have Admin rights to the Exchange Server, only Admin rights
to the local workstations. I believe this is a server setting but
need someone to confirm this.

Appreciate any help!
