This does not work on the newest version of Outlook. As not everyone updated at the same time, I'll keep this script alive, but for the new version, go to:
Removes the ad side bar from the Outlook Mail,the tags (ex: Photos) that appear before emails as well as the unsubscribe notices.
They frequently change the site inner workings around, which will lead to failure of the script by making important stuff disappear or useless stuff appear. I'll be updating it quickly though, so just update the style.
