Microsoft Exchange Server 2019 15.2.1118.7 CU12

Microsoft Exchange Server 2019 allows you to achieve more with rich Outlook encounters on telephones, tablets, work areas, and the Web.

Incorporation with Outlook, SharePoint, and OneDrive for Business assists you with encountering coordinated effort better while getting, altering, and sharing archives while never leaving 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, as well as more intelligently managing 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 cyphers and hashing algorithms protect your data.
  • Simpler Administration. Exchange Server 2019 makes administration easier for common tasks such as calendar and delegate management.
  • 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, 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.

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
  • E-Mail Traffic 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.

What’s new when upgrading from Exchange Server 2016 to 2019:
Security
  • Windows Server Core support: Running Exchange on a Windows deployment with less surface area means less attack surface area and fewer components to service.
  • Block external access to the Exchange admin centre (EAC) and the Exchange Management Shell: You can use Client Access Rules to only allow administration of Exchange from the internal network instead of using complex network and firewall rules.
  • TLS 1.2 is the only version that’s enabled by default: Exchange Server 2019 includes important changes to improve the security of client and server connections. The default configuration for encryption will enable TLS 1.2 only and disable support for older algorithms (namely, DES, 3DES, RC2, RC4 and MD5). It will also 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 in the operating system. For additional information, see Exchange Server TLS Guidance.
Performance
  • 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 bigger files, simpler management, and better search performance.
  • Faster, more reliable failovers: The changes to the search architecture result in significantly faster and more reliable failovers between servers.
  • Metacache database: Improvements at the core of Exchange’s database engine enable better overall performance and take advantage of the latest storage hardware, including larger disks and SSDs.
  • Modern hardware support: Exchange now supports up to 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.
Clients
  • Calendar – Do Not Forward: This is similar to 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 additional attendees.
  • Calendar – Better Out of Office: Additional options when you won’t be in the office. Key options include: add an event to your calendar that shows you as Away/Out of Office, and a quick option to cancel/decline meetings that will happen while you’re away.
  • Calendar – Remove-CalendarEvents cmdlet: Enables administrators to cancel meetings that were organized by a user that has left the company. Previously, conference rooms or meeting attendees would have these defunct meetings permanently on their calendars.
  • Assign delegate permission via 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.
  • Unified Messaging (UM). Unified Messaging has been removed from Exchange 2019. We recommend that Exchange 2019 organizations transition to Skype for Business Cloud Voice Mail.
