Is it possible to run it on OWA?

outlook.live.com

It's not clear if it can?

Because if it's a heavy client (an app/exe), I just better download OutLook exe, it will be complete and better

But if it's more like a browser plugin allowing for better UI on web page, then it's a great idea

You should clarify on the ReadMe

That would require exchange authentication which I don't believe he covered here.

So it's more like a skin?
