Body:
Millions of documents are stored today on OneDrive for Business that help people collaborate and get work done easily. But there are times when documents are sensitive and need an extra layer of protection. Office 365 provides Information Rights Management (IRM) capabilities, which helps you secure your information by encrypting it and applying an intelligent policy so that only specified internal and/or external people can “act” on your information.
For example, you can allow recipients to edit and print, but restrict them from forwarding to others. This policy is attached to the document, so it is applied no matter where your document lives—whether it’s in transit, on your laptop or a mobile device, or is a USB key—IRM lets you assign policies to email, SharePoint Online libraries, individual Office documents and other file types.
Safely sync protected documents
But when you move your data from the cloud, you want your information to stay safe. We are pleased to announce that you can now safely sync your IRM protected documents on OneDrive for Business. The IRM protection stays in place whether you open file on Office Online or on a local folder and continues to apply the settings even if you make edits to the file in both locations. Watch this video to learn more.
