OneDrive Folder share with Bussiness Account?

[gdgtsandmore]

Hi Guys,

I have a Problem. I have a privat Microsoft account and a Business account from my University.
The Problem is that OneDrive for Business doesn't support a native App for OS X.

So I tried to create a Folder in my Privat Account and shared it with the Business Account.
So wenn I drop a File in this Folder, the File is in both accounts.

But it doesn't work as I expected. (Like Dropbox)

When I share the Folder, I received only a Link per Mail, so I can look in the Folder from a Website, not from an App.
What could I do to make it work? Or is this "Dropbox-Like" Feature not supported yet?

Thank you very much for any help!!

Kind regards

Paul
