How to Delete an Address from the Outlook 'auto-complete' List

Outlook remembers every address you enter in any of the To:, Cc: or Bcc: boxes when you send a new email (although this behaviour can be switched off if preferred).

Unfortunately, Outlook also stores incorrect and defunct addresses in the auto-complete list, and these can be a nuisance if they keep appearing when you want to choose the correct address.

To remove a name or email address from Outlook's auto-complete list:

  1. Start a new email message in Outlook.
  2. Start typing the name or address you want to remove, and the unwanted address should appear in a drop-down list:

    Outlook 2013 autocomplete list

  3. Either float (do not click) your mouse pointer down over the entries in the list (use the scroll bar if available), or use the down-arrow key - Down-arrow key  - to select the unwanted address.  The selected entry is highlighted and shown with an 'X' indicating it can be deleted.
  4. Press the Delete key.  The unwanted address will disappear from the list, and should not reappear next time.
