An often asked question about Outlook 2007's Business card layout is how to change it for all contacts. While you can't globally change existing contacts, except by editing each contact, you can change the default which is used for new contacts by creating a custom contact form with the desired business card layout and publish it. Set it as the default Contacts form for new Contacts.
Using the custom form
Right click on the Contact folder, choose Properties and set the newly created custom form as the default form for the folder.
When you click New Contact, you'll use this form and all newly created contacts will use the new layout.
You can't change the form used by existing contacts, well, you can change the form, but the new business card layout won't be used. Use a tool listed below to change the message class to the new form.
