Have you contacted Microsoft yet?
https://support.microsoft.com/oas/default.aspx?gprid=1163&st=1&wfxredirect=1&sd=gn

If you have a support contract (which you probably do) you'll get a
very quick response if you choose the "security" option.

Whatever you do, do let everyone know what the problem turns out to be.
