OneDrive for Business: Getting Administrator's Access to User's Files and Folders
OneDrive for Business is a secure cloud-based solution for convenient telecommuting, remote access and private file sharing. Indeed, files stored on OneDrive are private by default: Users control access to the files they upload, so they can be seen by other employees only if they have been shared by the OneDrive owner. Even users with Global Administrator access cannot access files unless the OneDrive account holder has granted them the appropriate permissions.
