Thanks for all the feedback on this item. Its one the team hears and we are continuing to track this as part of our future roadmap. Please continue to share your thoughts and ideas here!
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.
