sent items in windows live mail

I can't seem to find a sent items folder in my windows live mail. On the left of my home pge I have quick views, then my account, then outbox then storage folders. Within storage folders I have all that was on my old outlook express before we change to Windows 7 and set up live mail (my son did this for us) There is a sent items folder within that but there is nothing in it. I used to easily be able to look through sent items (important sometimes) in Outlook express but I can;t seem to be able to do that now.
