Microsoft Exchange Server 2019 lets you accomplish more with rich Outlook experiences on phones, tablets, desktops, and the Web. Integration with Outlook, SharePoint, and OneDrive for Business helps you experience collaboration better when receiving, editing, and sharing documents without ever having to leave Outlook.

  • Security at the core.
  • Exchange 2019 runs on Windows Server 2019 Core, providing the most secure and reliable platform possible for your messaging infrastructure.
  • Improved Performance. Exchange 2019 uses available processor cores, memory, and storage more effectively than ever before and more intelligently manages internal system resources to help improve end-user performance.
  • Security. Exchange Server 2019 is more secure than any previous version out of the box, ensuring only the newest ciphers and hashing algorithms to protect your data.
  • Simpler Administration. Exchange Server 2019 makes administration easier for common calendar and delegate management tasks.
  • Mobile productivity. Connect, organize, and get things done on the go. Outlook mobile is the most secure and compliant way to access Exchange Online on your mobile device.

Microsoft Exchange Server 2019 brings a new set of technologies, features, and services to Exchange Server. This messaging platform 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.

Exchange Server uses a single building block architecture that provides email services for deployments of all sizes, from small organizations to the largest multi-national corporations.

Best Features of Microsoft Exchange Server 2019:

  • Service Monitoring
  • E-Mail Queue Monitoring
  • Client Access Connectivity (ActiveSync, OWA, POP, IMAP, etc.)
  • E-Mail flow Monitoring
  • Real-Time Change Auditing
  • Unauthorized Mailbox Logins
  • Mailbox Permission Changes
  • Mailbox Size Reports
  • Office 365 Reports

Server communication architecture

Communication between Exchange servers and past and future versions of Exchange occurs at the protocol layer. Cross-layer communication isn’t allowed. This communication architecture is summarized as “every server is an island”. This architecture has the following benefits:

  • Reduced inter-server communications.
  • Version-aware communications.
  • Isolated failures.
  • Integrated design inside each server.

Changes in Update For Exchange Server 2019 CU14 HU2

What’s new when upgrading from Exchange Server 2016 to 2019 :


  • Windows Server Core support: Running Exchange on a Windows deployment with much less surface area means much less attack surface area and fewer components to service.
  • Block external access to the Exchange admin center (EAC) and the Exchange Management Shell: You can use Client Access Rules to only allow administration of Exchange from the inner network as an alternative to using advanced network and firewall rules.
  • TLS 1.2 is the only version that’s enabled by default: Exchange Server 2019 includes necessary modifications to enhance the security of client and server connections. The default configuration for encryption will allow TLS 1.2 only and disable support for older algorithms (particularly, DES, 3DES, RC2, RC4, and MD5). It can even configure elliptic curve key exchange algorithms with priority over non-elliptic curve algorithms. In Exchange Server 2016 and later, all cryptography settings are inherited from the configuration specified within the operating system. For further information, see Exchange Server TLS Guidance.


  • Improved search infrastructure: The completely rebuilt search infrastructure for cloud scale and reliability in Exchange Online is now available in Exchange 2019. This new search infrastructure allows for the indexing of larger files, easier management, and higher search performance.
  • Faster, more reliable failovers: The modifications to the search architecture lead to significantly quicker and more reliable failovers between servers.
  • Metacache database: Improvements on the core of Exchange’s database engine allow better overall performance and make the most of the newest storage hardware, together with larger disks and SSDs.
  • Modern hardware support: Exchange now supports as much as 256 GB of memory and 48 CPU cores.
  • Dynamic database cache: The information store process employs dynamic memory cache allocation optimizing memory usage to active database usage.


  • Calendar – Do Not Forward: This is just like Information Rights Management (IRM) for calendar items without the IRM deployment requirements. Attendees can’t forward the invitation to other people, and only the organizer can invite extra attendees.
  • Calendar – Better Out of Office: Additional options whenever you won’t be within the office. Key options include: adding an event to your calendar that shows you as Away/Out of the Office, and a fast option to cancel/decline conferences that may occur while you’re away.
  • Calendar – Remove-CalendarEvents cmdlet: This enables administrators to cancel conferences that had been organized by a user who has left the company. Previously, conference rooms or assembly attendees would have these defunct conferences permanently on their calendars.
  • Assign delegate permission through PowerShell: Updates to the Add-FolderPermissions cmdlet so administrators can assign delegate permissions.
  • Email address internationalization (EAI): Email addresses that contain non-English characters can now be routed and delivered natively.
