Well, they have to be coming from somewhere. Outlook has at least two
address lists -- your contacts folder(s) and a nickname list built from
email addresses in your outgoing messages. You may also have access to a
corporate address list. The second list is still the most likely. If an
address pops up in the suggestion list that you don't want to see again,
just select it with the arrow keys and press Delete.
