We’re working on the ability to share a file or folder with a specific Microsoft Account.One Driver commented
The comments in the past demonstrate that most people are deceived heavily by the sharing functionality.
You have just the feeling you share with a microsoft account. In fact the shared files are just protected by owning the link not by the receivers account. Thats's the point!
It's a very crucial for data security and microsoft is misleading the users heavily in this point.
