Email Encryption

How do I Encrypt or make sure that my email is secure?

To encrypt an email you only need to include the keyword zEncrypt to the subject line:

Once encrypted, the recipient will either need to login to their Microsoft O365 email account to open their message or to use Microsoft’s O365 one-time password system to open the email and/or attachments.

End users will see one of the following messages if using a desktop client (email opens automatically in O365).


At Microsoft O365, you’ll see the following screen.  Click ‘Sign in with a work or school account’ to login with your O365 account or click ‘Or, sign in with a one-time passcode’ to have a code emailed to you.

If you’ve selected to use the one-time passcode, Microsoft will email you a code.  Copy and paste this into the screen at Microsoft to view the message.
