How to tell if a message you sent was CRES-encrypted

To determine whether a specific message you sent was encrypted by the Cisco Registered Envelope Service (CRES):

To determine if other messages were encrypted, you will need to look for them on Cisco's RES site. To do this, you must first register your Indiana University email address with CRES; once your address is registered, you can then view all encrypted sent messages, even ones sent before registration.

Register your IU email address

See Register your IU Exchange email account with CRES.

Search for an encrypted message

  1. Log into
  2. In the left menu, click Manage Messages.
  3. In the "Keyword" box, enter your search terms to find the message, and then click Search. To return all messages, leave the "Keyword" box blank, and click Search.
  4. Locate your message in the results.

If the message is not in the search results, it was not encrypted. If you believe that sensitive data has been wrongly disclosed, contact; see Report a suspected information or information technology (IT) security issue at IU.
