Introduction to Exchange Server 2019
Microsoft Exchange Server 2019 ExpertsMicrosoft Exchange Server 2019 is an on-premises release of Exchange that supports hybrid deployments with Microsoft 365 Exchange Online. A major feature is the ability to operate with Microsoft Windows Server 2019 Core, which reduces the target size exposed to a malware exploit and dispenses with unneeded services that waste network resources. Improvements over Exchange Server 2016 include better security, higher performance and capacity, and a variety of useful email client benefits.

The Mailbox and Edge Transport services plus admin utilities for Exchange Server 2019 need Microsoft Windows Server 2019. Microsoft Exchange Server 2019 no longer includes the Unified Messaging role, and therefore does not provide voicemail or auto attendant support. If your organization are moving from Microsoft Exchange Server 2013 or Microsoft Exchange Server 2016 and have deployed Unified Messaging (UM) services, Microsoft advises that you subscribe to the Cloud Voicemail Service available in Microsoft 365. Skype for Business 2019 and Microsoft Teams use this voice messaging service for Microsoft Exchange 2019 mailboxes. Generally, moving to Microsoft Exchange Server 2019 can call for an all-out modernization project.

Progent's Microsoft Gold-certified consultants can help your business with any facet of your migration to Microsoft Exchange Server 2019 from Exchange Server 2016, Microsoft Exchange 2013, or from legacy versions of Microsoft Exchange Server. Progent can provide online and on-premises expertise for system planning; implementing hybrid architectures; building pilot systems; installing high availability techniques such as hardware load balancing and database availability groups (DAGs); reviewing licensing compliance; setting up host servers based on Microsoft Windows Server 2019; configuring Windows Hyper-V virtual machines; upgrading your voicemail system; and calculating storage needs for virtual machines, critical databases and logs. Progent's Microsoft Exchange Server consultants are available to deliver as-needed support to help your business take care of an occasional technical bottleneck or Progent can deliver comprehensive project management or co-management expertise to ensure your Exchange Server 2019 migration is carried out on schedule and within budget.

Microsoft Exchange Server 2019 Architecture
Exchange Server 2019 is engineered on the efficient model introduced by Microsoft Exchange Server 2016. This design combines transport services, mailbox databases, and user access services in the Mailbox server. This significantly simplifies upgrades, configuration, scale, management, and troubleshooting compared to legacy versions of Exchange Server. The optional Edge Transport Server role comes with filtering agents that allow your perimeter network to manage Internet-facing mail traffic and protect against information leakage, spam and viruses.

Exchange 2019 Architecture Consultants

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

Microsoft Exchange 2019 Mailbox and Edge Transport servers and management tools need Standard or Datacenter editions of Microsoft Windows Server 2019. To administer these servers from a Windows client requires a current 64-bit release of Windows 10. (Exchange 2016 can be hosted by Microsoft Windows Server 2012 R2 and managed using Windows 8.1 or higher.) Progent offers remote or onsite Microsoft Windows Server 2019 planning and integration guidance, Windows 11 planning and migration consulting, and Windows 10 configuration consulting to help your organization update your Exchange environment.

Security and Performance Improvements in Exchange Server 2019
Microsoft Exchange Server 2019 is optimized for being hosted on Windows Server 2019 Core, which offers the safest environment for Microsoft Exchange Server 2019. You can also implement Exchange Server 2019 on Microsoft Windows Server 2019 with Desktop Experience, although this option exposes a larger attack service for malware exploits. By default, Microsoft Exchange Server 2019 uses TLS 1.2 transport protocol and replaces outdated ciphers. Several standards bodies call for the use of TLS 1.2. Another security 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 Exchange Server 2019 may be performed exclusively from within the security boundaries of your network.

For higher throughput and scale, Exchange Server 2019 can use up to 48 processor cores (as opposed to 24 for Exchange 2016) and 256GB of RAM memory (vs. 192GB for Exchange 2016). Suggested minimum in-box memory has been increased to 128GB. The well-tested cloud search technology incorporated in Microsoft Exchange Online has been brought to Microsoft Exchange Server 2019 for enhanced search response and faster database failovers, support bigger files for indexing, and simplify management. Exchange Server 2019 also allows larger disk drives. To offset the longer latency characteristic of high-capacity rotating disks, the new MetaCacheDatabase (MCDB) technology of Exchange Server 2019 allows you to set up solid state disk (SSD) caching when you implement Database Availability Groups (DAGs). Based on technology originally developed for Microsoft Exchange Online, MCDB can dramatically improve the responsiveness of the user environment. Throughput is also enhanced by changes in Exchange Server 2019 algorithms that make more RAM available for caching active database copies. These enhancements in Microsoft Exchange Server 2019 make it possible to configure each server to handle more users, integrate bigger disk drives, and increase the performance of many end-user operations.

Enhancements for Exchange Server 2019 Clients
Microsoft Exchange Server 2019 supports Outlook 2013, 2016 and 2019. Enhancements to the client experience include the Do-Not-Forward function that enables only a meeting's organizer to invite additional guests. Out-of-Office options have also been expanded. Also, a Remove-CalendarEvents cmdlet enables admins to remove events organized by a worker who no longer works for the company.

Cloud Voicemail for Exchange Server 2019
Microsoft Exchange Server 2019 does not provide the Unified Messaging (UM) services offered in previous versions 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 functions for Microsoft Exchange Server 2019 mailboxes. (Skype for Business 2019 still supports Exchange UM services for Exchange 2013 and Microsoft Exchange Server 2016.) Microsoft suggests that customers upgrading to Exchange 2019 migrate to Skype for Business Server 2019 and use Microsoft Cloud Voicemail Service. Exchange Server 2019 and Skype for Business 2019 can be deployed 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 clients have complete access to the latest voice messaging features.
