Is there any way to check how many activations are left on an Microsoft Office 3-pack license without calling Microsoft and asking them to check?

Is there a web-interface where you can test it yourself or something?

[Edit:] Well, I just ended up calling them anyway. Still, if anyone knows an answer to this for the future, I'd love to hear it - my calls usually drop, and I have to make sure to call them within their business hours in a different time zone, it'd be just so much easier if they had a web interface.
