We’re working on the ability to share a file or folder with a specific Microsoft Account.
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.Anonymous commented
Dropbox have had this for paid users for ages. One of the things that keeps me paying for Dropbox as opposed to moving over to OneDrive with my Office365 subscription.
Also like the related Dropbox feature to set expiry times for links when setting them up.
