Outlook has been widely criticized for security problems. In fairness, some of those could not reasonably have been predicted when the original security features of Outlook were being designed, and others result from implementation mistakes that have been fixed in service releases and hotfixes. Microsoft has worked hard to strengthen Outlook security by adding better attachment controls, complete support for S/MIME, and a range of other security features.
- Outlook expert Sue Mosher maintains what must be the most comprehensive Outlook-oriented site on the Web at slipstick.com. In particular, her write-up of the management options for the Outlook Email Security Update is a great summary of how to make the product do what you want it to do.
- The Microsoft Office Resource Kit site has complete information on the Outlook security package, setting up RPC over HTTP, using IRM, and other Outlook security topics.
- See Microsoft's site for more information on the Windows RMS package.
- To learn more than you ever wanted to know about S/MIME algorithms, protocols, and implementation considerations, visit the S/MIME Working Group of the Internet Engineering Task Force (IETF).
