Care to elaborate? Things like "doesn't work" are much to vague to work with
if you are looking for a serious answer. There is always more info you can
provide than just that.
Is it grayed out or no dialog pops-up when you clicked it?
Does it work in Outlook Safe Mode?
Start-> Run; outlook.exe /safe
Did you activate your version of Outlook already?
Did it ever work for you?
etc etc etc
