Outlook - Encrypting Email

York University enables the Office 365 encryption capabilities that allow the users to share protected email with anyone on any device. The encryption option is supported by both Outlook on the web, as well as the Outlook applications on both Windows and macOS.

There are various features available:

  • Send securely encrypted email to anyone (Encrypt-Only)
    • This message is encrypted. The recipients can’t remove encryption.
  • Prevent them from Forwarding the email (Do Not Forward)
    • Recipients can read this message, but cannot forward, print, or copy content. The conversation owner has full permission to their message and all replies.
  • Restrict access to only people with York University accounts (York University - Confidential)
    • This content is proprietary information intended for internal users only. This content can be modified but cannot be copied or printed.
  • Further restrict access to 'View Only' to people with York University accounts. (York University – Confidential View Only)
    • This content is proprietary information intended for internal users only. This content cannot be modified.

Messages sent as ‘York University - Confidential' can be sent to any email address, but to view them the recipient will be required to authenticate with their York University credentials.
