Microsoft Exchange Online is one of Microsoft's cloud-based applications in the Microsoft 365 product line enabled by Microsoft Azure. Exchange Online offers the advantages of reduced spending for physical infrastructure, easier management, dynamic capacity, high-availability, plus other benefits associated with public clouds instead of on-premises IT facilities.
