how do I open an existing contact with a new form?

[Kim]

I can create new contacts with a custom form but if I try
to open an existing contact it opens with the original
outlook supplied form.

You need to change the MessageClass on the existing items to point to your
new form's class. See
http://www.slipstick.com/dev/newdefaultform.htm#convert for several tools
and scripts to accomplish this.
