Introduction to Exchange Server 2019
Exchange Server 2019 ConsultingMicrosoft Exchange Server 2019 is a self-hosted version of Exchange that supports hybrid deployments with Microsoft 365 Exchange Online. A major feature is the ability to operate with Windows Server 2019 Core, which reduces the target size exposed to a cybersecurity attack and dispenses with unneeded server roles that waste network resources. Improvements over Exchange Server 2016 include enhanced security, higher performance and expandability, and a variety of useful Exchange client benefits.

The Mailbox and Edge Transport services plus admin utilities for Exchange Server 2019 require Microsoft Windows Server 2019. Exchange Server 2019 no longer includes the Unified Messaging role, and so does not provide voicemail or auto attendant services. If your organization are upgrading from 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 offered in Microsoft 365. Skype for Business 2019 and Teams use this voice messaging service for Exchange 2019 mailboxes. Generally, moving to Microsoft Exchange Server 2019 can demand a serious modernization effort.

Progent's Microsoft Gold-certified consultants can help you with any aspect of your upgrade to Microsoft Exchange Server 2019 from Exchange Server 2016, Microsoft Exchange 2013, or from legacy versions of Exchange Server. Progent can provide online and onsite guidance for solution planning; implementing hybrid architectures; building test lab environments; installing fault-tolerant technology including hardware load balancing and DAG groups; confirming server and CAL licensing compliance; setting up host servers based on Windows Server 2019; planning and deploying Windows Hyper-V virtual machines; upgrading your voicemail system; and calculating disk storage needs for virtual machines, databases and logs.

Exchange Server 2019 Architecture
Exchange Server 2019 is built on the efficient model used for Exchange Server 2016. This design consolidates transport services, mailbox databases, and client access services in the Mailbox server. This significantly simplifies migration, configuration, scale, administration, and troubleshooting compared to legacy versions of Exchange Server. The optional Edge Transport Server role includes filtering agents that allow your perimeter network to control Internet-facing mail traffic and protect against information leakage, spam and malware.

Exchange 2019 Architecture Experts

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

Exchange 2019 Mailbox and Edge Transport servers and management utilities need Standard or Datacenter version of Windows Server 2019. To administer 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 later.) Progent offers online or onsite Microsoft Windows Server 2019 planning and integration guidance, Windows 11 system design and migration assistance, and Windows 10 deployment guidance to help your organization update your Exchange environment.

Cybersecurity and Speed Improvements in Exchange Server 2019
Microsoft Exchange Server 2019 is optimized for being hosted on Windows Server 2019 Core, which provides the safest deployment for hosting Microsoft Exchange Server 2019. You can also run Microsoft Exchange Server 2019 on Microsoft Windows Server 2019 with Desktop Experience, although this alternative presents a bigger attack service for malware exploits. Out of the box, Exchange Server 2019 uses TLS 1.2 transport protocol and replaces legacy hashing algorithms. Some standards bodies require the use of TLS 1.2. Another cybersecurity improvement is the capability in Exchange Server 2019 to block outside users from connecting to the Exchange admin center (EAC) and the Exchange Management Shell. This allows you to make sure that the administration of Exchange Server 2019 may occur only from within the security boundaries of your system.

For higher throughput and scale, Exchange Server 2019 can utilize up to 48 processor cores (vs. 24 for Exchange Server 2016) and 256GB of RAM (as opposed to 192GB for Exchange Server 2016). Suggested minimum in-box memory has been upped to 128GB. The well-tested search technology incorporated in Microsoft Exchange Online has been brought to Microsoft Exchange Server 2019 to deliver improved search response and faster database failovers, allow bigger files for indexing, and streamline administration. Exchange Server 2019 also supports larger disk drives. To counter the increased latency characteristic of high-capacity rotating disks, the new MetaCacheDatabase (MCDB) technology of Exchange Server 2019 enables you to configure SSD caching when you deploy Database Availability Groups (DAGs). Powered by technology developed for Exchange Online, MetaCacheDatabase can significantly enhance the responsiveness of the end user environment. Performance is further enhanced by improvements in Microsoft Exchange Server 2019 algorithms that make more RAM available for caching active database copies. These improvements in Microsoft Exchange Server 2019 make it practical to configure each server to accommodate additional users, deploy higher capacity disk drives, and improve the responsiveness of many end-user processes.

Changes for Exchange Server 2019 Clients
Exchange Server 2019 supports Microsoft Outlook 2013, 2016 and 2019. Improvements to the client experience include the Do-Not-Forward function that allows only a conference's organizer to create invitations additional attendees. Out-of-Office (OOF) options have also been expanded. Also, a new Remove-CalendarEvents cmdlet enables administrators to remove calendar events organized by an employee who no longer works for the company.

Cloud Voicemail for Exchange 2019
Exchange Server 2019 does not include the UM services incorporated in previous releases of Exchange. UM services include voicemail and auto attendant. Microsoft Skype for Business 2019 depends on Cloud Voicemail Service to provide voice messaging support for Microsoft Exchange Server 2019 mailboxes. (Skype for Business 2019 still supports Exchange Unified Messaging services for Exchange 2013 and Microsoft Exchange Server 2016.) Microsoft suggests that customers moving to Exchange 2019 adopt Skype for Business Server 2019 and subscribe to Cloud Voicemail Service. Microsoft Exchange Server 2019 and Skype for Business 2019 can be set up in a hybrid environment with a combination of Microsoft Exchange Server 2019 and cloud-hosted Exchange Online mailboxes so that both local Exchange 2019 clients and Microsoft Exchange Online cloud users have full access to advanced voice messaging services.
