One of the key features in Office 365 is the ability to secure documents through easy to use Information Rights Management software (IRM). IRM has been part of the Microsoft suite of technologies for many years but with Office 365 it’s built right into the service and is very easy to use and configure.
Microsoft has announced that now IRM can be safely applied to synchronized documents using OneDrive for Business. This means that when you sync files that are protected by IRM they are automatically still safeguarded when they are synchronized to your local folder.
