The fine folks over at SearchExchange (in collaboration with MS Press) have excerpted chapter 13 from Secure Messaging with Microsoft Exchange Server 2003-- that just happens to be the Outlook security chapter. Their excerpt, "20 Tips on Securing Outlook in 20 Minutes", is well worth reading. It includes information on how to set up Outlook to use Windows Rights Management (including info on how to create your own RM templates), as well as information on controlling S/MIME through GPO templates, and how to set up and use RPC-over-HTTPs. f you like the chapter, buy the whole thing!
