Overview of Microsoft Exchange Server 2019
Exchange Server 2019 Design and SupportExchange Server 2019 is an on-premises version of Exchange that supports hybrid implementations that include Microsoft 365 Exchange Online. A major feature is support for Windows Server 2019 Core, which reduces the surface area vulnerable to a cybersecurity attack and eliminates unnecessary server roles that use up network resources. Refinements over Exchange Server 2016 include enhanced security, greater throughput and capacity, and a multitude of useful email client features.

The Mailbox and Edge Transport server roles plus management utilities for Microsoft Exchange Server 2019 require Microsoft Windows Server 2019. Microsoft Exchange Server 2019 does not include the Unified Messaging role, and therefore does not provide voicemail or auto attendant services. If you are moving from Microsoft Exchange Server 2013 or Exchange Server 2016 and have deployed Unified Messaging services, Microsoft advises that you subscribe to the Microsoft Cloud Voicemail Service offered in Microsoft 365. Skype for Business 2019 and Teams use this voice messaging technology for Exchange 2019 mailboxes. Generally, migration to Microsoft Exchange Server 2019 can call for a serious modernization effort.

Progent's Microsoft-certified consultants can help your organization with any phase of your migration to Exchange Server 2019 from Microsoft Exchange Server 2016, Microsoft Exchange Server 2013, or from end-of-support (EOS) releases of Exchange Server. Progent can provide remote and onsite expertise for solution design; implementing hybrid deployment models; creating test lab environments; incorporating high availability technology including HLB and database availability groups (DAGs); confirming licensing compliance; setting up host servers powered by Microsoft Windows Server 2019; configuring Hyper-V virtualization; modernizing your voicemail services; and estimating disk storage demands for virtual machines, critical databases and logs. Progent's Exchange Server experts are on call to deliver on-demand support to help your business take care of an occasional technical bottleneck or Progent can deliver comprehensive project management expertise to ensure your Microsoft Exchange Server 2019 upgrade is completed on schedule and on budget.

Microsoft Exchange Server 2019 Architecture
Exchange Server 2019 is built on the streamlined architecture introduced by Exchange Server 2016. This design combines transport services, mailboxes, and user access services in the Mailbox server. This dramatically simplifies migration, deployment, scale, management, and debugging in comparison to older versions of Microsoft Exchange Server. The Edge Transport Server role includes filtering agents that enable your perimeter network to control Internet-facing mail flow and guard against data leakage, spam and viruses.

Exchange 2019's compact design makes it easier to manage than older versions

Microsoft Exchange 2019 Mailbox and Edge Transport servers and management tools require Standard or Datacenter version of 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 2016 can be hosted by Microsoft Windows Server 2012 R2 and managed with Windows 8.1 or higher.) Progent offers remote or on-premises Windows Server 2019 planning and integration expertise, Windows 11 system design and upgrade consulting, and Windows 10 configuration expertise to help you modernize your email environment.

Cybersecurity and Speed Improvements in Exchange Server 2019
Exchange Server 2019 is optimized for running on Microsoft Windows Server 2019 Core, which provides the safest deployment for Microsoft Exchange Server 2019. You can also implement Microsoft Exchange Server 2019 on Microsoft Windows Server 2019 with Desktop Experience, although this option exposes a bigger target for malicious attacks. By default, Exchange Server 2019 utilizes Transport Layer Security protocol version 1.2 (TLS 1.2) and replaces outdated ciphers and hashing algorithms. Several standards organizations require the use of TLS 1.2. Another security enhancement is the ability in Exchange Server 2019 to block external users from connecting to the Exchange admin center console and the management shell. This means you can require that the management of Exchange Server 2019 may be performed exclusively from within the security boundaries of your network.

For improved throughput and expandability, Microsoft Exchange Server 2019 can utilize up to 48 processor cores (as opposed to 24 with Exchange Server 2016) and 256GB of RAM (as opposed to 192GB with Exchange Server 2016). Recommended minimum in-box RAM has been increased to 128GB. The well-tested search technology used by Microsoft Exchange Online has been ported to Exchange Server 2019 to deliver enhanced search performance and quicker database failovers, allow larger files for indexing, and streamline management. Microsoft Exchange Server 2019 also works with larger disk drives. To offset the longer latency characteristic of high-density rotating disk drives, the new MetaCacheDatabase (MCDB) feature of Microsoft Exchange Server 2019 allows you to configure solid state disk caching when you deploy Database Availability Groups. Based on features developed for cloud-hosted Microsoft Exchange Online, MCDB can dramatically enhance the quality of the user experience. Throughput is also enhanced by changes in Microsoft Exchange Server 2019 algorithms that make more RAM available for caching live database copies. These enhancements in Exchange Server 2019 make it possible to scale each Exchange server to accommodate more users, deploy higher capacity drives, and improve the responsiveness of many end-user operations.

Changes for Microsoft Exchange Server 2019 Clients
Microsoft Exchange Server 2019 supports Outlook 2013, 2016 and 2019. Improvements to the client interface include the Do-Not-Forward feature that enables only a meeting's organizer to create invitations additional guests. Out-of-Office (OOF) options have also increased. In addition, a new Remove-CalendarEvents cmdlet enables admins to remove events organized by an employee who has left the company.

Microsoft Cloud Voicemail for Exchange 2019
Microsoft Exchange Server 2019 does not provide the Unified Messaging services incorporated in previous versions of Microsoft Exchange. UM services include voicemail and auto attendant. Microsoft Skype for Business 2019 relies on Cloud Voicemail Service for voice messaging support for Microsoft Exchange Server 2019 mailboxes. (Skype for Business 2019 continues to support Exchange Unified Messaging services for Microsoft Exchange 2013 and Microsoft Exchange Server 2016.) Microsoft suggests that organizations moving to Microsoft Exchange 2019 migrate to Skype for Business Server 2019 and integrate Cloud Voicemail Service. Exchange Server 2019 and Skype for Business 2019 can be configured in a hybrid environment with a mix of Microsoft Exchange 2019 and cloud-hosted Exchange Online mailboxes so that both local Exchange 2019 users and Exchange Online cloud users have complete access to advanced voice messaging services.
