how to delete old email addresses

I have several old and incorrect emails in my email system, some of which are not even in my address book. When I start to type in these addresses, the autofill kicks in. How do I remove these old and incorrect email addresses?

All suggested addresses come from your address books. You need to find and delete them from your books. You have at least 2 default address books.
