By my understanding of FOSTA, it's actually left ambiguous as to whether or not Microsoft would be liable, especially since they no longer sell permanent licenses to consumers, but rather Software As A Service (eg., Office 365 is actually a software service, not a software product). I may be wrong, though.

And since OneDrive is a web hosting service, it's likely that if you save the file to your OneDrive folder instead of to your local hard drive, they are unambiguously liable.
