Overview of Microsoft Exchange Server 2019
Microsoft Exchange Server 2019 Design and SupportMicrosoft Exchange Server 2019 is an on-premises release of Exchange that supports hybrid implementations with Office 365 Exchange Online. A major feature is support for Windows Server 2019 Core, which reduces the surface area vulnerable to a cybersecurity exploit and eliminates unnecessary services that waste network resources. Improvements over Microsoft Exchange Server 2016 include enhanced security and compliance, higher performance and capacity, and a variety of new Exchange client features.

The Mailbox and Edge Transport services plus admin tools for Exchange Server 2019 need Microsoft Windows Server 2019. Exchange Server 2019 no longer includes the Unified Messaging (UM) role, and so does not offer voicemail or auto attendant services. If your business are upgrading from Exchange Server 2013 or Microsoft Exchange Server 2016 and have implemented Unified Messaging services, Microsoft recommends that you move to the Microsoft Cloud Voicemail Service offered in Office 365. Skype for Business 2019 and Microsoft Teams utilize this voice messaging service for Exchange 2019 mailboxes. Essentially, moving to Exchange Server 2019 can demand a comprehensive modernization effort.

Progent's Microsoft-certified consultants can assist you with any phase of your upgrade to Microsoft Exchange Server 2019 from Microsoft Exchange Server 2016, Microsoft Exchange Server 2013, or from end-of-support (EOS) versions of Microsoft Exchange Server. Progent can provide remote and onsite guidance for solution design; configuring hybrid architectures; building pilot systems; installing high availability technology including hardware load balancing and database availability groups (DAGs); reviewing licensing compliance; setting up host servers powered by Windows Server 2019; setting up Hyper-V virtualization; modernizing your voicemail services; and quantifying disk storage requirements for VMs, critical databases and logs. Progent's Microsoft Exchange Server experts are ready to deliver on-demand assistance to help you resolve an urgent technical impasse or Progent can provide end-to-end project management services to ensure your Microsoft Exchange Server 2019 upgrade is completed on schedule and on budget.

Microsoft Exchange Server 2019 Architecture
Microsoft Exchange Server 2019 is engineered on the efficient model used for Microsoft Exchange Server 2016. This architecture consolidates transport services, mailbox databases, and client access services in the Exchange Mailbox server. This significantly simplifies upgrades, deployment, expansion, management, and troubleshooting in comparison to legacy releases of Microsoft Exchange Server. The optional Edge Transport Server role includes filtering agents that enable your perimeter network to manage Internet-facing email traffic and protect against data leaks, spam and viruses.

Exchange 2019 Architecture Consultants

Microsoft Exchange 2019's architecture makes it easier to manage than legacy releases

Microsoft Exchange 2019 Mailbox and Edge Transport servers and management tools require Standard or Datacenter version of Microsoft Windows Server 2019. To manage these servers from a Windows client requires 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 online or onsite Microsoft Windows Server 2019 configuration guidance and Windows 10 integration guidance to help you modernize your Exchange environment.

Security and Performance Improvements in Microsoft Exchange Server 2019
Exchange Server 2019 is optimized for running on Windows Server 2019 Core, which offers the most secure deployment for Exchange Server 2019. You can also implement Exchange Server 2019 on Windows Server 2019 with Desktop Experience, although this alternative presents a larger attack service for malware attacks. Out of the box, Exchange Server 2019 utilizes Transport Layer Security protocol version 1.2 (TLS 1.2) and replaces legacy hashing algorithms. Several standards organizations require the adoption of TLS 1.2. Another security improvement is the capability in Microsoft Exchange Server 2019 to prevent outside users from accessing the Exchange admin center (EAC) and the Exchange Management Shell. This allows you to require that the administration of Exchange Server 2019 may occur only from within the security perimeter of your system.

For higher throughput and expandability, Exchange Server 2019 can utilize up to 48 processor cores (vs. 24 for Exchange Server 2016) and 256GB of RAM memory (vs. 192GB for Exchange 2016). Suggested minimum in-box memory has been increased to 128GB. The well-tested search technology used by Microsoft Exchange Online has been ported to Microsoft Exchange Server 2019 for improved search response and more rapid database failovers, support bigger files for indexing, and simplify administration. Microsoft Exchange Server 2019 also works with larger storage drives. To offset the increased latency characteristic of high-density rotating disks, the new MetaCacheDatabase (MCDB) feature of Microsoft Exchange Server 2019 enables you to set up SSD caching when you deploy DAGs. Based on technology originally developed for cloud-hosted Exchange Online, MetaCacheDatabase can dramatically enhance the responsiveness of the user experience. Throughput is further enhanced by improvements in Microsoft Exchange Server 2019 algorithms that make more RAM available for caching live database copies. These enhancements in Microsoft Exchange Server 2019 make it possible to configure each Exchange server to handle more users, deploy bigger disk drives, and improve the performance of common end-user operations.

Changes for Exchange Server 2019 Clients
Exchange Server 2019 can be used with Microsoft Outlook 2013, 2016 and 2019. Enhancements to the client experience include the Do-Not-Forward function that enables only a conference's organizer to invite additional attendees. Out-of-Office features have also increased. In addition, a new Remove-CalendarEvents cmdlet allows administrators to remove calendar events organized by a worker who is no longer with the business.

Microsoft Cloud Voicemail for Exchange 2019
Exchange Server 2019 does not include the UM services incorporated in previous releases of Exchange. Unified Messaging services include voicemail and auto attendant. Skype for Business 2019 depends on Microsoft Cloud Voicemail Service for voice messaging support for Microsoft Exchange Server 2019 mailboxes. (Skype for Business 2019 continues to support Exchange UM services for Exchange 2013 and Microsoft Exchange Server 2016.) Microsoft recommends that customers moving to Microsoft Exchange 2019 migrate to Skype for Business Server 2019 and subscribe to Microsoft Cloud Voicemail Service. Exchange Server 2019 and Skype for Business 2019 can be deployed in a hybrid environment with a combination of Microsoft Exchange Server 2019 and Exchange Online mailboxes so that both on-premises Exchange 2019 clients and Exchange Online cloud clients have complete access to advanced voice messaging features.
