Send an Encrypted Email
In conjunction with your YaleConnect Office 365 account, email encryption provides an additional layer of security when members of the Yale community send email using YaleConnect Office 365.
Email encryption converts the message from readable plain text into scrambled cipher text. Only the recipient can view the message. This process also encrypts any attachments sent with encrypted messages.
How do I create an encrypted email?
- Using your YaleConnect Office 365 email account, in the beginning of the subject line of the message include the word encrypt with brackets around it: [Encrypt] or [encrypt]. For example, SUBJECT: [encrypt] Please review today
- Encrypting an email message will also encrypt any attachments included with the message.
How much does it cost?
There is no charge for the service, however, you must have a YaleConnect Office 365 account.
