Explanations of different encryption choices
Encryption only
This option means that the email is encrypted, allowing only the intended recipient to read the content. It protects the message in transit, so that if someone else tries to intercept it, they won't be able to read it. However, it is possible for the recipient to forward, print, or copy the message, depending on other settings.
Do Not Forward
The recipient can't forward the email to others. It can also mean that the recipient can't copy or paste text from the message, depending on your organization's settings. In some cases, it may even be impossible for the recipient to print or download documents attached to the email.
