Delete old autocompleted email addresses

[BillS]

When I start typing an email address, sometimes Outlook
will offer several options to auto complete those
addresses. How do I delete the options which are no
longer good email addresses?

Remove individual addresses from the autocompletion cache by highlighting
the entry when presented in the suggested names list (use your arrow key to
migrate to the entry) and then hitting your Delete key before you tab out of
the field. To clear the entire cache, follow the instructions here:
