What can we expect from Exchange Server 2019?
On July 24, 2018, the Exchange Product Group released the preview version of Exchange Server 2019. This version is the third version of modern Exchange Server. Like the previous versions, Exchange Server 2019 benefits from the product developments tested and implemented in Exchange Online. But not all features available in Exchange Online are available in the on-premises version of Exchange Server. Additionally, not all features that are announced for the new release will be available when the RTM build is released. That is something that we have learned with previous releases of the product.
