We have OneDrive but I'm not aware of anybody in our large company using it. Instead our team spend extra money on Dropbox, and Box. OneDrive is clunky, hard to use. It does not even integrate well with Office365, let alone other apps. In terms of UX, OneDrive is a disaster.

Google Drive has a fatal flaw that kills its enterprise growth: you have to register your primary domain, no sub-domains allowed. This is fine for start-ups, but in enterprise, if one team sign up for Google Drive, no other teams can sign up separately! In a large company, it's next to impossible for our team to find that original team to pair up for Google services, if they're willing to share the services at all, budget issues and all that.
