Microsoft is being super lazy
"What's likely happening here is that Microsoft is being super lazy and checking the user-agent string to see which version of its code it should serve to the browser"

“In one piece of mail people were suggesting that Office had to work equally well with all browsers and that we shouldn’t force Office users to use our browser. This Is wrong and I wanted to correct this.”, billg
