Sending Encrypted UTD Email


Want to add a padlock to your email messages? When you need to protect the privacy of an email message, encrypt it. Encrypting an email message in Outlook means it's converted from readable plain text into scrambled ciphertext.

To read an encrypted email, recipients must authenticate with their credentials or use a one-time passcode.

Encryption Methods

Automatic Encryption

By default, if you write an email to an external recipient(s) that contains sensitive data (such as a UTD ID), it will be detected by EOP’s rules and be encrypted when sent.

Mobile/ Outlook Web

You can send an encrypted message to an external email address by typing "[encrypt]" in the email's subject line. 

Example of encrypted email received with Read the message button.

Email Encryption allows users to send encrypted emails to people inside or outside the organization. To view encrypted messages, recipients will receive a one-time passcode (guests), or UTD students, staff, and faculty can log in with their UTD credentials.
