I go to create a new e-mail (with Outlook 2007) and fill in the 'To' field
with one alpha character. I see a drop down box (to speed things along) but
at least one of those 'suggestions' is not valid; that particular address
does not exist. It did exist at one time though.

How do I flush out those helpful though inaccurate\old e-mail addresses?
Thanks, DH
