How to delete cached autocomplete email addresses in outlook

Outlook has an automatic completion 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 wasn’t in your contact list, and it will still add that to the auto complete list.

The problem comes in 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 fix this problem, there are two ways around this. The easiest way is this:

+ Start typing in the address that shows up incorrectly.
+ Hit the Down arrow key to select the auto completed address.
+ Hit the Delete key to delete the auto complete address
