When an "Encrypt Email Message" action is triggered, the recipient can decrypt the resulting encrypted message in the following way:

Use a web browser. Recipients of encrypted messages who are not using Email Encryption Client receive an email notification that provides a website link allowing the recipient to view the content of the message.

Note:

Decrypting messages with Microsoft Outlook Web Access 2007 is not supported.

Microsoft Outlook 2016 mail client is supported for decrypting messages.

Below is a sample encrypted email notification message:

  1. Double-click the attached Encrypted_Message.htm file, which opens in your default web browser, as shown below.
  2. Click Open my email, and if not yet registered, fill in the registration information on the subsequent pages. If you have already registered for this service, the encryption site displays your decrypted email at this point.
    Note:

    The Open my email function may not work reliably with some web-based email systems. If the button does not work, the customer can save the attachment to a local computer and then open it again.

    Recipients only need to register once. After registering with the Email Encryption service, the recipient will be able to view decrypted email in a browser window by clicking Open my email.

  3. For enhanced security, match a CAPTCHA image, type and confirm a pass phrase, and select and answer three security questions. Upon successful registration, the email encryption site sends an activation message to the registered email account.
