Become a Trusted Source

When you send an encrypted Email, the email address receiving the email is also required to have a secure digital ID (email security certificate). The digital ID verifies that a receiver is a trusted source. Any provider can become a trusted source by obtaining a digital ID and setting it up on their system. These steps explain how to obtain, then import a digital ID into Microsoft Outlook 2013 so that providers can receive encrypted email messages.

  1. Obtain a digital ID (Email Security Certificates) from a Certificate Authority (e.g. Comodo (https://www.comodo.com/home/email-security/free-email-certificate.php).
  2. In Microsoft Outlook 2013, click File, Options, Trust Center, Trust Center Settings..., Email Security.
  3. Check two options:
    • Add digital signature to outgoing messages.
    • Send clear text signed message when sending signed messages
  4. Under Digital IDs, click Import/Export...
  5. Click OK.
  6. Click OK.
  7. Send a clear text test email to the provider.

Note: Instructions may be different for other versions of Outlook, even though it has supported email signatures and encryption for many years.
