Please note that the email recipient will be provided instructions on how to access the secure message. This is done via a one time password. We recommend you send a test email to an external email address you manage (ie: your personal email). This will guide you through the workflow, and you can then instruct email recipients on how to view the secure message, if they are unfamiliar with the process.
