Finding my email address in MS Exchange

I use MS Exchange, when I need to give an outsider my email address, I don't know what to give since the directory conveniently hides this from me.

To get my address:
Compose mail -> click on "To..." -> find your name in the dir --> right click on your name
Click on Properties -> go to the tab labelled "Email Adress"

your email is on the first line --
