How can I ensure that mail sent from my Exchange account to an outside address is encrypted by CRES?

If you want to ensure that a specific message will be encrypted by the Cisco Registered Envelope Service (CRES), you can do so by including Secure Message or Confidential (case insensitive) in the subject line. The system will also trigger on words that include "confidential", including "confidentially" and "non-confidential".

All other messages sent outside of the IU mail servers are scanned for certain sensitive data; if the scan determines that such information appears in a message or its attachments, the message is automatically encrypted. Messages with Secure Message or Confidential in the subject line are not scanned.

Note:
If you do not use these keywords to force encryption of your message, you will receive a notification when CRES encrypts it. See Why did I receive a Message Encryption Notification?

If you want to ensure that all of your outgoing messages to outside addresses will be encrypted, you can create a template for your email client that will add Secure Message or Confidential to all of your mail.

To determine whether a message you sent was encrypted, see At IU, how can I tell if a message I sent was encrypted by CRES?
