If you receive a password-protected Registered Envelope and you have not registered with the service, click the Register button. If the Register button is not displayed, leave the password field empty, and click the Open button to begin the registration process. For more information about opening a Registered Envelope for the first time, see the Help Guide.
Attachments can be sent by either replying to a received secure message (from within the CRES envelope) or by initiating a secure message.
