Introduction to Microsoft Exchange Server 2019
Exchange Server 2019 ExpertsExchange Server 2019 is an on-premises version of Exchange that supports hybrid deployments that include Microsoft 365 Exchange Online. A headline feature is support for Microsoft Windows Server 2019 Core, which minimizes the target size exposed to a cybersecurity assault and eliminates unnecessary services that waste network resources. Refinements over Exchange Server 2016 include enhanced data protection, greater throughput and capacity, and a multitude of useful email client features.

The Mailbox and Edge Transport services plus admin utilities for Exchange Server 2019 need Windows Server 2019. Exchange Server 2019 does not include the UM role, and so does not provide voicemail or auto attendant services. If your organization are migrating from Exchange Server 2013 or Exchange Server 2016 and have implemented Unified Messaging services, Microsoft advises that you subscribe to the Cloud Voicemail Service offered in Microsoft 365. Skype for Business 2019 and Microsoft Teams utilize this voice messaging technology for Exchange 2019 mailboxes. Essentially, migration to Exchange Server 2019 can demand a comprehensive update effort.

Progent's Microsoft Gold-certified consultants can help your organization with any aspect of your move to Microsoft Exchange Server 2019 from Exchange Server 2016, Microsoft Exchange Server 2013, or from legacy versions of Microsoft Exchange Server. Progent can provide remote and onsite expertise for solution design; configuring hybrid deployment models; creating test lab environments; installing fault-tolerant techniques including HLB and DAG groups; reviewing licensing compliance; configuring host systems powered by Windows Server 2019; setting up Hyper-V virtualization; upgrading your voicemail services; and estimating storage needs for VMs, critical databases and logs. Progent's Microsoft Exchange Server experts are available to provide as-needed assistance to help your business take care of an occasional technical issue or Progent can provide end-to-end project management or co-management services to ensure your Exchange Server 2019 upgrade is carried out on time and within budget.

Exchange Server 2019 Design
Exchange Server 2019 is built on the efficient model introduced by Exchange Server 2016. This design combines transport services, mailboxes, and user access services in the Exchange Mailbox server. This significantly simplifies upgrades, deployment, expansion, management, and troubleshooting compared to legacy releases of Exchange Server. The Edge Transport Server role includes filtering agents that allow your perimeter network to control Internet-facing email traffic and protect against information leakage, spam and malware.

Exchange 2019 Architecture Experts

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

Exchange 2019 Mailbox and Edge Transport servers and management tools need Standard or Datacenter version of Windows Server 2019. To manage these servers from a Windows client requires an up-to-date 64-bit version of Windows 10. (Exchange Server 2016 can be run on Microsoft Windows Server 2012 R2 and managed using Windows 8.1 or later.) Progent can provide online or on-premises Windows Server 2019 configuration consulting, Windows 11 system design and migration consulting, and Windows 10 integration guidance to help your organization modernize your Exchange environment.

Cybersecurity and Performance Improvements 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 run Microsoft Exchange Server 2019 on Microsoft Windows Server 2019 with Desktop Experience, although this option exposes a bigger target for malware exploits. Out of the box, Exchange Server 2019 utilizes Transport Layer Security protocol version 1.2 (TLS 1.2) and replaces outdated ciphers and hashing algorithms. Several standards bodies mandate the use of TLS 1.2. Another cybersecurity enhancement is the ability in Exchange Server 2019 to block external users from accessing the Exchange admin center (EAC) and the Exchange Management Shell command-line interface. This allows you to require that the administration of Microsoft Exchange Server 2019 can be performed exclusively from inside the security perimeter of your system.

For higher throughput and scale, Microsoft Exchange Server 2019 can utilize up to 48 processor cores (vs. 24 for 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 proven cloud search technology incorporated in Exchange Online has been brought to Microsoft Exchange Server 2019 to deliver improved search performance and more rapid database failovers, support bigger files for indexing, and simplify management. Microsoft Exchange Server 2019 also allows bigger storage drives. To counter the longer latency associated with high-capacity rotating disk drives, the new MCDB feature of Microsoft Exchange Server 2019 enables you to configure solid state disk (SSD) caching when you implement DAGs. Based on technology developed for Microsoft Exchange Online, MetaCacheDatabase can significantly enhance the responsiveness of the user environment. Performance is further increased by improvements in Exchange Server 2019 algorithms that allow more RAM for caching active database copies. These enhancements in Microsoft Exchange Server 2019 make it practical to configure each Exchange server to accommodate more users, integrate larger drives, and increase the performance of common end-user processes.

Changes for Exchange Server 2019 Clients
Microsoft Exchange Server 2019 can be used with Microsoft Outlook 2013, 2016 and 2019. Improvements to the client experience include the Do-Not-Forward feature that enables only a conference's organizer to create invitations additional guests. Out-of-Office options have also increased. Also, a Remove-CalendarEvents cmdlet enables administrators to remove events organized by an employee who no longer works for the company.

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