You'd have to use a customized Outlook form (IPM.Note) and make that the
default message form.
If this is to be distributed to others you'd be far better off writing the
code as a COM addin.

And even with a custom form, the user can still invoke the Address Book with Ctrl+SHift+B and input recipients.
