Force outlook stop showing facebook picture.

Like many others user I have the same issue, when I send an email it show my ex facebook's profile picture (I closed my facebook account). I HAVE NEVER VINCULATE THEM, there was no vinculation right now, there's nothing I can do. If you tick the option Don't show public content from third-party networks. It won't show the picture when I READ the emails, no when I send them. I have read many topics about this and in april Microsoft didnt give a solution, I thinks its time to solve this issue. I use my email for work and It should be serious, not with facebook pictures.
