S/MIME support for Exchange Outlook Web Access (OWA) was introduced in Exchange 2003. In Exchange 2007 SP1, we are adding S/MIME support back and making it more reliable and powerful. Below, is a short introduction to S/MIME and simple end-to-end steps for how to use S/MIME with OWA on Exchange Server 2007 SP1.
Introduction: The S/MIME feature in OWA is about secure messaging - enabling OWA to send and receive signed and encrypted email. Signed messages allow the recipient to verify that the message came from the person that the message claims to be from. Encrypted messages allow the sender to ensure that only the intended recipients can read messages that are sent to them. While it’s true that the message is unreadable to anyone who might intercept it while in transit, it is also true that even the Exchange administrator cannot read these messages.
