Last week we announced a new feature called Personal Vault that will be available soon for OneDrive consumer accounts. See this blog post for more details.
We have no plans to bring Personal Vault to our Commercial customers at this time, but continue to make investments in advanced security features that are unique to the Commercial service.

While I get that Personal Vault is not available in commercial accounts the fact that there is not a standalone method of activating Personal Vault is frustrating for those of us who keep an Office 365 Business account for our own email.
It would be nice if you could somehow allow a user with both a business and personal account unlimited files in the personal vault up to the free storage cap.
I literally just subscribed and canceled a standalone OneDrive subscription on my personal account because I didn't notice that the vault wasn't even included.
