Announcing Exchange Server 2019 Public Preview

Tuesday, July 24, 2018

Today Microsoft announced the public preview for Exchange Server 2019. It is likely to reach general availability later this year.

Exchange 2019 continues to deliver the security, performance, and improved administration and management capabilities that customers expect, along with additional enhancements. Exchange Server 2019 can now be installed on Windows Server 2019 Core. This greatly reduces the attack surface of Exchange Server.

Search has been completely rewritten (again) to provide better and faster results. A side effect of this change is that it provides faster DAG failovers.

Performance improvements include reengineering to support bigger and better hardware. Exchange 2019 can now run on servers with up to 48 cores and 256GB RAM. Exchange 2019 will support the use of SSDs for tiered storage when it is released (it currently is not enabled in the preview build). More details on this will be released in September at Microsoft Ignite in Orlando.

A very important thing to know is that Exchange Server 2019 no longer supports Unified Messaging. Customers who currently use UM will need to move to another voicemail solution before they move to Exchange 2019.
