drop down box contents when entering recipient's address

Occasional Visitor
On outlook.com, on a Win10 PC, entering the first two letters of a recipient's email addresses causes a drop down box to display. Some of the drop down addresses are not in the user's contact list. How can the contents of the drop down display be controlled? Dave22

That's the so-called auto-complete (or name) cache, you can clear entries from it by highlighting the entry and pressing the delete (x) button.
