Top Secret Messenger (TSM) is a powerful and secure public-encryption add-on for Outlook Express. It is completely integrated into this program, allowing users to encrypt outgoing messages automatically by simply clicking on the Send button! Similarly, it automatically decrypts incoming messages as soon as they arrive.

If you have already purchased a registered version of Top Secret Messenger with some other plugin and would like to use it with Outlook Express, please purchase the cheaper standalone Outlook Express plugin that does not include TSM.
