Clearing the Auto-Complete Email Address Cache in Outlook

Print Friendly, PDF & Email

Outlook has an automatic completion list for any email address that you try to type into the To or CC fields. This feature does not pull from the contacts or address book, because you may have tried to email somebody that isn’t in your contact list.

The problem arises when you put in a bad address, and then every time you go to type in the email address, the incorrect one appears in the auto-complete list.

To remove an email address from your auto-complete list:

  1. In the To: or CC: field, begin typing in the address that shows up incorrectly.
  2. A list of email addresses that match what you have typed will appear in a dropdown list below the field.
  3. Click the X next to the address you wish to delete.
