What is email encryption and how does Microsoft 365 use it?

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 (TLS) 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.

Thank you! Helped me find my way through it. I used Business Premium licensing to get this ability.

Will it encrypt all emails or will you be able to select the emails that you want to have encrypted?

Hi, we have setup the encryption for a few external recipient domains, however they are annoyed with the process of logging in with their email ID each time when they receive any new emails from us. Is there no option wherein they aren't required to verify their identity by logging in each time. I could not find any client AIP agent that can help circumvent validation by the recipients.
