Microsoft Exchange 2016 is the latest version of this popular email and calendaring software and includes many features to make productivity a safe and secure endeavor. This version includes data loss prevention with more sensitive information types available now rather than as an upgrade. Enhanced auditing is also available for better reporting and easier integration with third-party apps. Simplicity and smarts play key roles in this version of Exchange as its simple architecture makes it easier to plan and scale tasks. The email inbox is more personalized and has more intelligent features and faster search capabilities to allow your employees to get more done. You can also use Exchange 2016 on phones, tablets, desktops and the web as this server powers the latest Outlook. Note that this is an Open License and is designed for businesses with between two and 250 computers. Open licenses are perpetual licenses and the program term is two years.
The Edge Transport role is typically deployed in your perimeter network, outside your internal Active Directory forest, and is designed to minimize the attack surface of your Exchange deployment. By handling all Internet-facing mail flow, it also adds additional layers of message protection and security against viruses and spam, and can apply transport rules to control message flow.
