Document tracking, a feature in Azure Rights Management (Azure RMS), enables document owners to track activities about the sensitive files they share with others. Through the web, you can track activities such as recipients who open files, unauthorized users who are denied access, and the latest state of files.
You can also view the geographical locations where files were accessed, and revoke access to a shared file. This feature is available as part of an Azure RMS Premium subscription, the Microsoft Enterprise Mobility Suite, or the Microsoft Enterprise Cloud Suite.
