Microsoft All in One Account

I've just been going through my microsoft account and cleaning everything up and all of the services, and I had a question about one feature:

A while ago, probably when I first made my account when outlook.com entered beta, it used my facebook picture as my automatic profile picture for my microsoft account, which would update as I edited facebook.

Since, it has been disabled, by me probably. I don't know why, and I would really like to re-enable that.
