Add the Certificate into your Outlook:

  • Launch Outlook and select File > Options in the main menu.
  • Select Trust Center > Trust Center Settings…
  • Select Email Security and click the Import/Export button to import the S/MIME certificate.
  • Browse to the S/MIME certificate file location in your computer.
  • Note that the S/MIME certificate bundle is also referred to in Outlook as a Digital ID or Security Profile.
  • Locate the Security Profile (i.e. S/MIME certificate) to import to Outlook.
  • Enter the password associated with the S/MIME certificate. If you obtained the certificate as a .p12 or .pfx file from a certificate authority, they must have also given you the password.
  • The certificate’s private key was encrypted with the password, so if you lost it, you won’t be able to import the certificate into Outlook.
  • Unless you need enhanced security, leave the security level set to Medium and tap OK on the pop-up dialog box.
  • Allow protected access to your S/MIME certificate’s private key.

Turn On S/MIME Signing and Encryption

We’re now going to set up Outlook to digitally sign outgoing mail with the new S/MIME identity. This will allow our email contacts with a S/MIME-compatible email software to:

  • Authenticate messages we send them
  • Automatically import our public key so they can use it in the future to send us encrypted emails.
  • Click the Settings button, under Encrypted email.
  • Name your security settings and make sure Cryptography format is set to S/MIME.
  • Check Default Security Settings for this cryptographic format
  • Check Security Settings for all cryptographic messages

Signing Certificate

  • Click Choose… to browse to the S/MIME certificate file and and click OK to confirm.

Encryption Certificate

  • Click Choose… to browse to the S/MIME certificate file and confirm.
  • Finally, check Send these certificates with signed messages


Encrypted Email Settings

  • Go back to the Email Security tab and set the default options for S/MIME email as below.
  • Check Encrypt contents and attachments for outgoing messages
  • Check Add digital signature to outgoing messages

You should now be able to send emails digitally signed with your S/MIME identity and receive encrypted emails. Outlook should automatically import the S/MIME public key of anyone who sends you a signed email, so you should also be able to send encrypted messages to anyone who has sent you a signed message before.
