The key development changes
As stated during Microsoft Ignite 2018, the newest on-premises release is available only in the Volume Licensing model and is aimed mainly at large enterprises. Greg Taylor started the conference by acknowledging that there are customers who prefer to keep their data on-premises, instead of going into the cloud. No doubt, Microsoft will do everything they can to adapt their online environments to fit even the most demanding security, reliability and dependability needs of the current on-prem users.
Although those statements let us suspect the future of Microsoft’s on-premises server solutions, they do not tell us much about what is new in Exchange 2019. The fact is that to fit the needs of the largest enterprises, which are the most important on-premises users, Microsoft completely redefined the way the on-premises software is built.
From now on, the on-premises Exchange and Exchange Online will have their code branched. What does it mean? The on-premises Exchange will not be an “offline copy” of its online counterpart anymore. Since most on-premises organizations value dependability over innovation, future Exchange 2019 updates will put more stress on security and less on the functionalities department. The ultimate goal is to ensure a consistent on-premises experience. The CU updates with potential functionality changes will be separated from security updates, so that admins can decide what to implement. At the same time, Exchange Online will offer the highest level of innovation. Despite the focus on the innovation, end-user experience and functionalities, the security aspect in unlikely to be overlooked, let’s hope.
Exchange 2019 requirements
A complete list of Exchange 2019 system requirements, is available at this site. Below, I list a shortened version.
Windows Server 2019 regardless whether it is the Mailbox or Edge Transport role (Windows Server Core is recommended but not required)
.Net Framework 4.7.2
AD FFL 2012R2+
Coexistence with Exchange 2013+ (although there are a few exceptions)
128-256 GB RAM for Mailbox Server, minimum of 64 GB for Edge Transport
With the great focus on scalability and performance, the minimum RAM requirement might come as a bit of surprise. According to the documentation, Exchange 2016 required only 8 GB of RAM. As far as I have tested it, small Exchange 2016 organizations worked just fine with 8-16 GB. While it is possible to install Exchange 2019 with less memory, it will not let you experience any of the performance-boosting functionalities.
Almost every official post about Exchange 2019 states that it is recommended to install this newest version of Exchange on Windows Server Core. Mind that it does not mean that you cannot install it with the Desktop Experience.
