This is an issue on the Office 365 Home Page. It includes files from email I haven't opened yet, takes up approximately 1/3 of the page, and is generally unhelpful.
It's another instance of Microsoft deciding for the user what the user needs/wants, instead of users having control of what is actually useful in their particular contexts. Users, not Microsoft, should control the user's computing experience.
