Well, if there's some sort of cloud feature allowing you to share documents you write with others, it would make sense you would have to allow Microsoft to "reformat, display, and distribute" for the purpose of providing you that service.

However, the terms of service says "To the extent necessary to provide the Services to you and others, [...] and to improve Microsoft products and services". So they're saying they can use your content not just to provide you service, but to provide other people service and to improve all Microsoft products.

That would be me sharing a specific document with a specific person. If their terms sepcified that they would only ""reformat, display, and distribute" to people we personally give permission to then that would be fine, but it doesn't.

The word 'necessary' can do a lot of heavy lifting.
