Email Encryption: Encrypting Email Messages
Brookdale’s Office 365 Email supports sending encrypted email messages. Encryption is the process of encoding information so that only an authorized recipient can decode and consume the information. Brookdale’s Office 365 uses encryption in two ways: One is by implementing encryption in the Office 365 service, and the second is by enabling you to send encrypted messages to external email services.
Sending Encrypted messages within our organization
In the Office 365 service, we make use of encryption on the platform, where it works by default, and you don’t have to configure anything. All messages sent within our organization are automatically sent over a secured connection using Transport Layer Security (TLS) to encrypt the sending and receiving of email. No additional action is required to send an encrypted email message.
Sending to External Email Recipients
Send encrypted email messages to external services by entering “Encrypt:” in the subject line before the text of the subject. (Note: you must include the colon)
The encrypted message is delivered to a recipient’s inbox just like any other email message, but it contains an HTML file attachment. After opening the attachment, the recipient uses a one-time passcode to view the message on the Office 365 Message Encryption portal. The email includes instructions for viewing the encrypted message, as in the following example.
The recipient can read the encrypted message as follows:
- Follow the instructions in the email message to download and save the attachment.
- Open the message.html file in the email.
- Select Use a one-time passcode.
- The passcode is sent to another email message. Get the passcode, enter it, and then click CONTINUE.
- The recipient can now view your message.
