Email, Encryption of email messages

This page describes encryption methods currently available for University email.

Email is NOT designed to be a secure message exchange. That said, we have enabled the following features to help make it more secure:

  • The campus email relays are configured for "opportunistic TLS". As long as the receiving server/domain can handle a TLS connection, the data is sent via an encrypted path; otherwise the email is sent to the receiving server in the default "in the clear" mode.

  • The campus Exchange servers connect to the campus relays via TLS  by default.

  • Outlook can be configured to encrypt your outbound email. While instructions are available online and can be used to set up encryption for your email, Technology Services is only able to provide best-effort support for setting up encryption.

  • Privacy and Information Security is looking at encryption products that may serve as a possible campus solution.
