What are Transport Rules in Exchange Server designed to do?

Transport Rules in Exchange Server are specifically designed to control the flow of email messages within the organization. They operate on messages as they pass through the transport system and can apply various actions based on predefined conditions set by the administrator. This includes monitoring for specific keywords, phrases, or patterns in email content or attachments and taking actions such as blocking messages, redirecting them, adding disclaimers, or notifying compliance teams.

These rules are highly customizable, allowing organizations to enforce policies on email usage and protect sensitive information. As a result, administrators can ensure that communications comply with company policies and legal requirements, enhance security, and maintain the integrity of email communications.

Other options, such as managing user authentication, providing calendar scheduling, or backing up database configurations, relate to different functionalities within Exchange Server and do not pertain to the management of email flow and direct handling of messages, which is the primary purpose of Transport Rules.
