I did some testing. You can type in any domain in front of that domain and it will show you the page in question. Visiting the main page just shows a sad looking page — not very professional if it is legit.
I checked the whois data for that domain and it also looks phishy. It is using a Dynamic DNS service and the registrant address is “One Microsoft Way”. So either its a scam or Microsoft has gotten really sloppy about their proxy service.
I use OpenDNS but they had not yet blocked this domain. I attempted to report it to them and they referred me to phishtank.com who had no record of the domain.
On OpenDNS I was able to block the domain so my home is protected. Consider this a warning.
