If you’re using Outlook for Windows, Outlook for Mac, or a third-party email app, youll receive an email message with instructions for how to read the encrypted message. You can gain access using your Microsoft account or your Microsoft 365 account.

What Is Email Encryption

Encryption is a process through which any particular data or text is made unintelligible to the common people. Email encryption means encrypting emails so that not any random person can comprehend the message. Every encrypted text has a key and only the person with that key can decrypt that email and read it in its original format. So to decrypt encrypted emails in Outlook, the user needs proper information at his end.

When Does It Make Sense To Send Encrypted Mail

Some people still associate encryption in general with government spies and shadowy hackers who must protect their identity to escape the law. In reality, encrypted mail has become a modern necessity because billions of people around the world use email to send and receive sensitive information, such as bank account statements, business documents, and personal correspondence.

The problem is that email users often forget or dont realize that email was never meant to play such an important role in our lives and be used to transfer sensitive information. Instead, it was intended to facilitate messaging between people who more or less knew one another, so data security and privacy werent important priorities of emails original creators.

When you send unencrypted messages over the internet, you risk having your personal information stolen or exposed by an opportunistic cybercriminal, and only email encryption can give you the peace of mind that comes with knowing that nobody can read your messages.

As such, it makes sense to encrypt as many emails as possible and use the most robust email encryption method available. Ideally, you want your email encryption to be applied automatically each time you send a message to eliminate the possibility of you forgetting to apply it yourself.

    How Microsoft 365 Uses Email Encryption

    Criptext for Gmail: Secure Email, Read Receipts, and ...

    Encryption is the process by which information is encoded so that only an authorized recipient can decode and consume the information. Microsoft 365 uses encryption in two ways: in the service, and as a customer control. In the service, encryption is used in Microsoft 365 by default you don’t have to configure anything. For example, Microsoft 365 uses Transport Layer Security to encrypt the connection, or session, between two servers.

    Here’s how email encryption typically works:

    • A message is encrypted, or transformed from plain text into unreadable ciphertext, either on the sender’s machine, or by a central server while the message is in transit.

    • The message remains in ciphertext while it’s in transit in order to protect it from being read in case the message is intercepted.

    • Once the message is received by the recipient, the message is transformed back into readable plain text in one of two ways:

    • The recipient’s machine uses a key to decrypt the message, or

    • A central server decrypts the message on behalf of the recipient, after validating the recipient’s identity.
