What is the effect of applying a 'Do Not Forward' rule in Microsoft Information Protection?

Applying a 'Do Not Forward' rule in Microsoft Information Protection is a critical feature designed to enhance the security of sensitive information shared via email. This rule specifically prevents the recipient from forwarding the email to others, thereby maintaining control over who has access to the content.

The primary intent behind this functionality is to protect sensitive data by restricting unauthorized distribution. When an email is marked with the 'Do Not Forward' rule, it ensures that even if the recipient has access to the email, they cannot share it with anyone else, either intentionally or unintentionally, thus minimizing the risk of data leaks.

While editing or deleting the email may be concerns in data protection, the specific focus of this rule is to restrict forwarding. As such, recipients might still be able to edit the content of the email or take other actions not related to forwarding. This targeted functionality is vital for organizations that handle confidential information and wish to enforce strict controls around how that information can be shared.
