What’s new in Exchange Server
Exchange Server 2019 brings a new set of technologies, features, and services to Exchange Server, the messaging platform that provides email, scheduling, and tools for custom collaboration and messaging service applications. Its goal is to support people and organizations as their work habits evolve from a communication focus to a collaboration focus. At the same time, Exchange 2019 helps lower the total cost of ownership whether you deploy Exchange 2019 on-premises or provision your mailboxes in the cloud.
