Does the recipient of a SkyDrive folder have to have SkyDrive to open my folder? What is the minimal OS the recipient needs ? I sent folders to a recipient who has a Microsoft Login, but is using Vista OS. She could not open the folders. First I sent the folders to her iPad email address, then to her PC email address, neither worked.

I sent the folders to her email address and copied myself. Of course, I was able to open the folders, but she couldn't. Does the email address of the recipient make any difference, i.e. Charter. Net?
