Exchange 2019 roadmap
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.
