Overview
Through the Cisco Secure Email Encryption Service (CSEES), you can lock or unlock, and expire or unexpire encrypted messages; you can also check the read status of a sent message. To do these tasks, you must first register your Indiana University email address with CSEES; once your IU address is registered, you can then manage all encrypted sent messages, even messages sent before registration.
