In Outlook 2003, when I compose a new message, and then
click the To or Cc button, the contacts list displays
names that are sorted by the contact's first name. Is
there a way to automatically switch existing contacts to
display last name first?

I can do so for NEW contacts

In Outllok 2003 help, to change the name format for
existing contacts, it says: I

n the Display As field, type the name in the format that
you want.  Repeat for each contact you want to change.

There must be an easier way than going into each of my
contacts and retyping last name first, isn't there??
