For years, systems administrators have been asking how they can protect the content of Outlook messages from being copied, forwarded, or printed and make messages inaccessible after a specified date. Until recently, the only available solutions have been third-party tools and services. Citing its Trustworthy Computing initiative and the need to protect the privacy of digital information, Microsoft has stepped into the document- and message-protection product area by introducing Windows Rights Management Services (RMS) for Windows Server 2003 (http://www.microsoft.com/windowsserver2003/rm). Don't confuse RMS with Digital Rights Management (DRM), the Microsoft platform for providing secure distribution of video, audio, and other digital-media files so that users can play those files only on computers that have an authorized license key. Rather, the Information Rights Management (IRM) functionality that RMS implements lets organizations limit who can work with a document or an email message and what the authorized user can do with the document or message. . . .
