Is there a way, either built-in to Outlook 2003 or through third party
software that will display contacts in a alphabetical list when
composing a mail message? Specifically, the user wants to be able to
select a letter, e.g. "A", "B", "C", etc... when composing a message
(when clicking the "To" field in the mail form) that will pull up an
alphabetical listing of contacts from the address book.

I know this capability resides in OWA, but I have yet to find a
solution for Outlook 2003. Any assistance would be greatly appreciated.

Thanks,
Ryan
