Getting rid of email addresses in Microsoft Outlook autocomplete/autofill!

 For months I have been trying to determine a way of removing unwanted, or mistyped email address from Microsoft Outlook autofill or autocomplete for email addresses.  There seems to be no option in outlook.com....but there is!!!!  You have to go into "Rules" (gear icon in upper right, then view all outlook settings at bottom of window that pops up) and then start making a rule that includes the email address you want to get rid of...almost magically, an "X" will appear next to all the addresses, and you can click it!
