Explore The New Features Of Microsoft Exchange Server 2019

As Microsoft Released New Exchange Server 2019 is now available and can be downloaded from the Volume Licensing Service Center. Exchange Server 2019 is designed to deliver security, performance and improved administration and management capabilities.Let’s Check What are the new Features Available.


  • 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 Exchange admin center (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.


  • 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 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 failover over 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. This new feature updates the Exchange database engine when MCDB is enabled to allow support for larger JBOD disks (up to 16TB) with the added feature of using an SSD to store mailbox meta information like mailbox folder structure and items metadata. Using this feature allows for faster logon times, reduced latency, and faster overall response times. Although you do not need to install an SSD if you just want to host Exchange Databases, you will need an SSD (1 SSD disk for each 3 JBOD disks is recommended) in order to enable the MCDB feature.
  • Modern hardware support: Exchange now supports up to 256 GB of memory and 48 CPU cores.This is a huge increase compared to Exchange 2016, which supports 24 CPU cores and 192GB of memory.
  • Dynamic database cache: The information store process employs dynamic memory cache allocation optimizing memory usage to active database usage. Previously, each Exchange database, actively mounted or passive, received the same amount of cache memory assigned from Exchange. The DDC now allocates additional cache memory to active databases and reduces memory of passive ones. This allows the server to service more reads from cache memory, thus providing better overall server performance.


  • 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.
