Introduction to Microsoft Exchange Server 2019
Exchange Server 2019 is a self-hosted release of Exchange that supports hybrid implementations that include Microsoft 365 Exchange Online. A headline enhancement is support for Windows Server 2019 Core, which minimizes the target size exposed to a cybersecurity exploit and dispenses with unneeded services that use up network resources. Improvements over Microsoft Exchange Server 2016 include better security, greater throughput and expandability, and a multitude of novel Exchange client features.
The Mailbox and Edge Transport services as well as management utilities for Exchange Server 2019 need Microsoft Windows Server 2019. Microsoft Exchange Server 2019 does not include the Unified Messaging (UM) role, and therefore does not offer voicemail or auto attendant services. If your organization are upgrading from Microsoft Exchange Server 2013 or Exchange Server 2016 and have implemented Unified Messaging (UM) services, Microsoft recommends that you move to the Cloud Voicemail Service offered in Microsoft 365. Skype for Business 2019 and Microsoft Teams use this voice messaging technology for Exchange 2019 mailboxes. Essentially, moving to Exchange Server 2019 can require a comprehensive modernization project.

Exchange Server 2019 Design
Microsoft Exchange Server 2019 is built on the streamlined model introduced by Exchange Server 2016. This architecture consolidates transport services, mailbox databases, and user access services in the Exchange Mailbox server. This dramatically simplifies upgrades, deployment, scale, management, and debugging compared to legacy releases of Exchange Server. The Edge Transport Server role comes with filtering agents that enable your perimeter network to manage Internet-facing email flow and guard against information leakage, spam and malware.
Microsoft Exchange 2019 Mailbox and Edge Transport servers and management utilities need Standard or Datacenter version of Microsoft Windows Server 2019. To manage these Exchange servers from a Windows client you need an up-to-date 64-bit version of Windows 10. (Microsoft Exchange Server 2016 can be run on Microsoft Windows Server 2012 R2 and managed using Windows 8.1 or higher.) Progent can provide remote or on-premises Windows Server 2019 deployment consulting, Windows 11 system design and upgrade consulting, and Windows 10 configuration expertise to assist you update your Exchange environment.
Security and Performance Enhancements in Microsoft Exchange Server 2019
Exchange Server 2019 is optimized for running on Windows Server 2019 Core, which provides the safest environment for hosting Microsoft Exchange Server 2019. You can also implement Exchange Server 2019 on Windows Server 2019 with Desktop Experience, although this alternative exposes a larger target for malicious assaults. Out of the box, Exchange Server 2019 uses Transport Layer Security protocol version 1.2 (TLS 1.2) and replaces legacy ciphers. Some standards bodies require the use of TLS 1.2. Another security improvement is the capability in Exchange Server 2019 to prevent external users from connecting to the Exchange admin center console and the Exchange Management Shell. This allows you to make sure that the administration of Microsoft Exchange Server 2019 can occur exclusively from within the security perimeter of your system.
For improved throughput and scale, Exchange Server 2019 can use as many as 48 processor cores (vs. 24 with Exchange Server 2016) and 256GB of RAM (as opposed to 192GB with Exchange 2016). Recommended minimum in-box memory has been upped to 128GB. The well-tested search infrastructure used by Microsoft Exchange Online has been brought to Exchange Server 2019 to deliver enhanced search performance and more rapid database failovers, support bigger files for indexing, and streamline administration. Microsoft Exchange Server 2019 also supports bigger storage drives. To counter the increased latency characteristic of high-density rotating disk drives, the innovative MetaCacheDatabase (MCDB) technology of Exchange Server 2019 allows you to set up SSD caching when you deploy Database Availability Groups. Based on technology developed for Exchange Online, MCDB can significantly improve the responsiveness of the end user environment. Throughput is also increased by improvements in Microsoft Exchange Server 2019 algorithms that allow more RAM for caching active database copies. These enhancements in Microsoft Exchange Server 2019 make it possible to scale each server to handle more users, deploy higher capacity disk drives, and increase the responsiveness of many end-user operations.
Enhancements for Exchange Server 2019 Clients
Exchange Server 2019 supports Microsoft Outlook 2013, 2016 and 2019. Improvements to the client experience include the Do-Not-Forward function that allows only a conference's organizer to invite other guests. Out-of-Office (OOF) features have also increased. In addition, a new Remove-CalendarEvents cmdlet enables admins to remove events organized by a worker who no longer works for the company.
Microsoft Cloud Voicemail for Exchange Server 2019
Microsoft Exchange Server 2019 does not include the UM services incorporated in prior versions of Exchange. UM services include voicemail and auto attendant. Microsoft Skype for Business 2019 depends on Microsoft Cloud Voicemail Service to provide voice messaging support for Exchange Server 2019 mailboxes. (Skype for Business 2019 still supports Exchange Unified Messaging services for Exchange 2013 and Microsoft Exchange Server 2016.) Microsoft recommends that customers upgrading to Exchange 2019 migrate to Skype for Business Server 2019 and use Cloud Voicemail Service. Microsoft Exchange Server 2019 and Skype for Business 2019 can be configured in a hybrid architecture with a combination of Exchange Server 2019 and Exchange Online mailboxes so that both local Exchange 2019 clients and Exchange Online cloud users have complete access to advanced voice messaging services.
This voice messaging environment provides voicemail answering and deposit; voice-to-text and text-to-voice services; voice mail access through Outlook or Skype for Business; voicemail management via the M365 portal; and hybrid deployment support for Exchange mailboxes on premises or in the cloud. Administration is made easier because of a uniform set of management utilities for both Microsoft Exchange 2019 and Exchange Online mailboxes. Progent can assist your organization to adhere to best practices to configure a hybrid network model that enables all your Exchange clients to access the Cloud Voicemail service.
