ah come on give me a more challenging question!! j/k!!
Go to tools.. (up top) then chose Options... then click on the tab that says Send... If you look about half way down that pop up page you will see "Automatically complete email addresses when composing" (it may be worded a bit different according to your windows year!)
If you uncheck that box, hit apply then okay and there you go! :-)
Hope this helps!
