Microsoft® Outlook/Outlook Express

Microsoft Outlook can serve as both a standard Internet e-mail client for those who use either POP or IMAP servers and as a Microsoft Exchange client for corporate customers. Microsoft Outlook provides two security features to help send confidential information across the Internet and to make sure that e-mail comes from the person it says it’s from: digital signatures and encryption. These features use a private key and a public key, the basis of PKI. When using RSA Certificate Manager software, Microsoft Outlook provides a robust, secure method of communicating over the Internet.
