Behaving as designed. Fax numbers are, in fact, electronic addresses. The
standard behavior for the Outlook Address book is to display all electronic
addresses (both fax and e-mail). That behavior cannot be changed. The only
way to prevent the display of fax numbers is to store them in a different
field or to disguise them (e.g., precede them with an alpha character) so
that Outlook won't recognize them as phone numbers.
There are also a number of utilities available that can do this for you
automatically. Some are listed here:
