Encryption and UCO Email


What is email encryption

Encryption is the process by which an email is encoded so that only an authorized recipient can access the content within the email. With Office 365 Message Encryption, UCO employees can send encrypted emails from Outlook from any type of device.

Types of UCO email encryption

UCO email allows for 4-type of email encryption:

  1. Encrypt-Only:  Encrypts the message so only intended recipients can open it. They can still forward, print, or copy the content of the message.

  2. Do Not Forward: Encrypts the message and will not allow the recipient(s) to forward, print, or copy the content of the message.

  3. University of Central Oklahoma – Confidential:  This content is proprietary information intended for internal users only. This content can be modified but cannot be copied and printed. For emails between UCO employees only.

  4. University of Central Oklahoma – Confidential View Only:  This content is proprietary information intended for internal users only. This content cannot be modified. For emails between UCO employees only.

If no encryption type is specified the email is not encrypted and anyone will be able to open, print, and forward the email upon receipt.

Send an encrypted e-mail
