You can learn more about Dynamic Database Cache from Welcome to Exchange Server 2019! video and slides. We also changed the way database caching works to allocate more memory to active database copies, again improving the end user experience. We also talked about this in our Email Search in a Flash! Accelerating Exchange 2019 with SSDs session at Ignite. We’re adding dual storage read/write capabilities to Exchange Server 2019 using Solid State Drive (SSD) technology to provide a super-fast cache of key data for improving end user experience. We’ve re-engineered search using Bing technology to make it even faster and provide better results, and in doing so have made database failovers much faster, and administration easier. With our improvements, Exchange Server can use up to 48 processor cores and 256GB of RAM.

Performance: We’ve done significant work to allow Exchange Server to take advantage of larger core and memory packed systems available in market today. To understand how this affects coexistence with earlier versions, please reference our previous series of posts on TLS. We also built Exchange Server 2019 to only use TLS 1.2 out of the box, and to remove legacy ciphers and hashing algorithms. Exchange Server 2019 will be fully compatible with version 1809, and the refreshed version. We’re aware all media for Windows Server 2019 and Windows Server, version 1809 has been temporarily removed and Microsoft will provide an update when refreshed media is available. You also have the option of installing Exchange 2019 onto Windows Server 2019 with Desktop Experience, but we have worked hard to make sure running Exchange on Server Core is the best choice for our code. Exchange Server 2019 installed on Windows Server 2019 Core provides the most secure platform for Exchange. In fact, we recommend installing Exchange Server 2019 onto Windows Server 2019 Server Core.

Security: Exchange Server 2019 requires Windows Server 2019.

Here is a selection of other key features in Exchange Server 2019: During that session we talked for the first time about how the code paths between on-premises and online have separated, and the impact to on-premises customers – in short, less code churn and more stability. If you haven’t yet seen the session delivered at Microsoft Ignite 2018 we suggest you watch the video and download the slides here. Exchange Server 2019 is designed to deliver security, performance and improved administration and management capabilities attributes our largest on-premises customers expect from Exchange. We’re pleased to announce the final build of Exchange Server 2019 is now available and can be downloaded from the Volume Licensing Service Center.
