This is not a commercial to be aired on tv, just an internal promotion skit to rally the salestroops at the most recent Microsoft Global Exchange conference. It's meant to entertain and amuse the troops, while hammering home the sales angle. The angle being: Gmail snoops on your mail. It's kind of funny if you're easily amused. And the showtune is rather sticky, sing along to Geee-mail man. The production values are as bad as in House Party, but will a censored version be even funnier? Naah.
Note the the name of the fake office is Contoso Ltd.
