Introduction to Exchange Server 2019
Exchange Server 2019 Design and SupportMicrosoft Exchange Server 2019 is an on-premises version of Exchange that supports hybrid deployments with Microsoft 365 Exchange Online. A headline feature is the ability to operate with Microsoft Windows Server 2019 Core, which reduces the surface area vulnerable to a malware assault and dispenses with unnecessary services that waste network resources. Improvements over Microsoft Exchange Server 2016 include enhanced security and compliance, greater performance and expandability, and a multitude of new email client benefits.

The Mailbox and Edge Transport server roles plus management utilities for Exchange Server 2019 require Windows Server 2019. Microsoft Exchange Server 2019 does not include the Unified Messaging role, and therefore does not offer voicemail or auto attendant services. If you are upgrading from Microsoft Exchange Server 2013 or Microsoft Exchange Server 2016 and have implemented Unified Messaging services, Microsoft recommends 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 Microsoft Exchange 2019 mailboxes. Generally, moving to Exchange Server 2019 can demand an all-out update effort.

Progent's Microsoft Gold-certified consultants can assist your business with any facet of your upgrade to Microsoft Exchange Server 2019 from Exchange Server 2016, Exchange Server 2013, or from legacy releases of Microsoft Exchange Server.

Microsoft Exchange Server 2019 Architecture
Microsoft Exchange Server 2019 is engineered on the streamlined model used for Exchange Server 2016. This architecture combines transport services, mailboxes, and user access services in the Exchange Mailbox server. This dramatically simplifies upgrades, configuration, expansion, administration, and debugging compared to older releases of Exchange Server. The optional Edge Transport Server role comes with filtering agents that enable your perimeter network to control Internet-facing mail traffic and protect against data leakage, spam and viruses.

Microsoft Exchange 2019's architecture makes it easier to manage than older versions

Exchange 2019 Mailbox and Edge Transport servers and management tools need Standard or Datacenter version of Microsoft Windows Server 2019. To administer these Exchange servers from a Windows client you need an up-to-date 64-bit version of Windows 10. (Exchange 2016 can be run on Windows Server 2012 R2 and administered using Windows 8.1 or higher.) Progent offers online or onsite Windows Server 2019 deployment expertise, Windows 11 system design and upgrade assistance, and Windows 10 deployment consulting to assist your organization update your email solution.

Cybersecurity and Performance Enhancements in Microsoft Exchange Server 2019
Exchange Server 2019 is tuned for being hosted on Windows Server 2019 Core, which provides the most secure deployment for Exchange Server 2019. You can also implement Microsoft Exchange Server 2019 on Windows Server 2019 with Desktop Experience, although this option presents a bigger target for malware assaults. Out of the box, Exchange Server 2019 uses Transport Layer Security protocol version 1.2 (TLS 1.2) and removes outdated ciphers. Some standards organizations mandate the use of TLS 1.2. Another cybersecurity enhancement is the ability in Exchange Server 2019 to prevent external users from accessing the Exchange admin center console and the Exchange Management Shell. This means you can require that the management of Microsoft Exchange Server 2019 can occur exclusively from inside the security boundaries of your network.

For higher performance and expandability, Exchange Server 2019 can use as many as 48 processor cores (vs. 24 for Exchange Server 2016) and 256GB of RAM memory (as opposed to 192GB for Exchange 2016). Recommended minimum in-box memory has been increased to 128GB. The well-tested search infrastructure used by Microsoft Exchange Online has been ported to Microsoft Exchange Server 2019 for improved search response and faster database failovers, support bigger files for indexing, and streamline administration. Microsoft Exchange Server 2019 also supports bigger storage drives. To counter the increased latency associated with high-density spinning disks, the new MetaCacheDatabase feature of Microsoft Exchange Server 2019 allows you to set up solid state disk caching when you deploy Database Availability Groups. Powered by technology developed for cloud-hosted Exchange Online, MetaCacheDatabase can dramatically improve the responsiveness of the end user environment. Performance is also increased by improvements in Exchange Server 2019 algorithms that allow more RAM for caching live database copies. These enhancements in Exchange Server 2019 make it practical to configure each server to support more users, deploy higher capacity disk drives, and improve the responsiveness of many end-user processes.

Changes for Microsoft Exchange Server 2019 Clients
Exchange Server 2019 works with Microsoft 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 options have also been expanded. Also, a Remove-CalendarEvents cmdlet allows administrators to delete events organized by an employee who has left the business.

Cloud Voicemail for Exchange 2019
Exchange Server 2019 does not include the UM services offered in previous releases of Microsoft Exchange. Unified Messaging services include voicemail and auto attendant. Microsoft Skype for Business 2019 relies on Microsoft Cloud Voicemail Service for 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 suggests that organizations upgrading to Microsoft Exchange 2019 adopt Skype for Business Server 2019 and subscribe to 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 2019 and Exchange Online mailboxes so that both on-premises Exchange 2019 clients and Exchange Online cloud clients have complete access to the latest voice messaging services.
