It is a nuisance that when you send a reply to someone who is not on the contacts list they are automatically added. Also that you can not delete existing contacts when using an android based phone when logging in in the normal way without the hotmail app for Android. The technology is there only not implemented. I use a Chinese Regmi android phone and want to have as much as possible a direct line without extra installed software apps in order to login to my Hotmail account this to satisfy my emotional based privacy principle.
