The Outlook add-in allows you to receive and send secure emails using your Outlook email client. This gives you the convenience of managing both your secure and non-secure emails from a single email client.
When you receive a secure email and click on it, the add-in will coordinate with the TrustX service to authenticate you, then will present the secure email information on your screen.
If you want to send a secure email, you may compose it as you would normally, including any attachments, and the add-in allows you to select the desired level of trust for your secure email.
This TrustX add-in will not affect your normal (non-secure) emails in any way.
