Ensure that mail sent from your 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] (case insensitive, with square brackets) in the subject line.

UITS recommends that you use [Secure Message] to trigger CRES encryption now, but the previously used phrases confidential and secure message (without brackets) will be supported until January 2019.

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] in the subject line are not scanned.

If you do not use these keywords to force encryption of your message, you will receive a notification when CRES encrypts it. See If you 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] to all of your mail.

To determine whether a message you sent was encrypted, see How to tell if a message you sent was CRES-encrypted.
