You can remove unwanted addresses from the address auto-complete list that appears when you start typing recipients in Outlook.

Complete an Address That is Old or Mistyped?

Outlook remembers every address you have typed in a To:, Cc: or Bcc: field. This is good: when you start keying in a name or address, Outlook automatically suggest the contact in its entirety.

Unfortunately, Outlook remembers the mistyped and old as well as the correct and current — and suggest it indiscriminately.

Fortunately, getting rid of entries you no longer want to appear in the auto-complete list is easy.
