Currently, Outlook.com uses opportunistic Transport Layer Security (TLS) to encrypt the connection with a recipient's email provider. However, with TLS, the message might not stay encrypted after the message reaches the recipient's email provider. In other words, TLS encrypts the connection, not the message.

To provide the best-in-class encryption to our customers, Microsoft has deprecated Transport Layer Security (TLS) versions 1.0 and 1.1 in Office 365 and Office 365 GCC. However, you can continue to use an unencrypted SMTP connection without any TLS. We don't recommend email transmission without any encryption.

Check the subkeys for each SSL/TLS version for both server and client. Each protocol's state is controlled by two keys: Enabled and DisabledByDefault. If the Enabled value is 1 and the DisabledByDefault value is 0 or missing, the protocol is enabled.

You should see ?TLS? or a TLS version identifier in the header. It may say ?TLS1. 2? or ?TLS1. 3.? If you see this, TLS was used to secure this message.
