Outlook remembers every address you enter in the To, Cc, and Bcc fields of an email message. Then, when you enter the first few letters of a name or email address, Outlook automatically suggests contacts that match. If Outlook remembers mistyped and old contacts that you don't want to appear in the autocomplete list, get rid of those entries.
