Microsoft Exchange Server 2016 is a leading enterprise messaging system that delivers email, calendar, voice mail, and contacts to users on a variety of devices through the Outlook client. Exchange Server 2016 provides reliable, scalable, enterprise-class email with compliance and e-discovery features integrated with Microsoft SharePoint and Skype for Business. Exchange Server 2016 supports people and organizations as their work habits evolve from a communication focus to a collaboration focus. The database design in Exchange Server 2016 reduces the storage I/O requirements, thereby optimizing Exchange for cost-effective, low-speed storage. Exchange deployment must be appropriately sized to meet not only specific message profile requirements, but also growth and high availability requirements.
