Click contacts at the bottom left of your Hotmail inbox screen to manage your contacts.
From there you can manage your contacts in the middle of your screen, or click a category (list) of contacts to manage from the left side navigation on your screen.
I was not clear in my question. How can I delete an email which is not in my list of contacts, but which comes up when I type the first couple of letters of another contact. For example, I wrote something to Frank and did not put his name in my contact list. Now whenever I type Fr his name comes up along with any other names beginning with Fr such as Fred. I am now using windows 7. Hope this is clearer to you. Thanks for you attempt at helping me.
