You probably already know that Exchange 2019 RTM has been released and even CU1 is about to come too.
But what’s interesting about 2019 is that it has a lot of new features, some that lot of people wanted to have in legacy versions especially for security, performance, resiliency and scalability.
As per Microsoft Security has been improved to suit the needs of corporations removing all vulnerable ciphers and follow best practices.
Security: Exchange Server 2019 requires Windows Server 2019. In fact, we recommend installing Exchange Server 2019 onto Windows Server 2019 Server Core. Exchange Server 2019 installed on Windows Server 2019 Core provides the most secure platform for Exchange. 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.
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. Exchange Server 2019 will be fully compatible with version 1809, and the refreshed version.
We also built Exchange Server 2019 to only use TLS 1.2 out of the box, and to remove legacy ciphers and hashing algorithms. To understand how this affects coexistence with earlier versions, please reference our previous series of postson TLS.
Regarding Performance, Microsoft has released the following statement:
Performance: We’ve done significant work to allow Exchange Server to take advantage of larger core and memory packed systems available in market today. With our improvements, Exchange Server can use up to 48 processor cores and 256GB of RAM.
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.
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 also talked about this in our Email Search in a Flash! Accelerating Exchange 2019 with SSDs session at Ignite.
We also changed the way database caching works to allocate more memory to active database copies, again improving the end user experience. You can learn more about Dynamic Database Cache from Welcome to Exchange Server 2019!video and slides.
The improvements we have made to Exchange Server 2019 will enable you to scale to a larger number of users per server than ever before, use much larger disks, and see the latency of many client operations being cut in half.
Installing Exchange 2019 on Core is something that’s been recently supported, along with other features like in-place upgrade from Exchange 2016 to Exchange 2019.
In this guide we’ll go through the process of installing Exchange 2019 using PowerShell starting from naming the server, joining it to the domain and installing prerequisites of Exchange 2019.
Configuring Static IP address:
In order to give a static IP address to the machine from Windows Core we’ll be using the following script:
Assuming you have subnet 192.168.18.0 with mask /24 and gateway 192.168.18.1. we will use the below script to provide the machine with an IP.
$wmi = Get-WmiObject win32_networkadapterconfiguration -filter “ipenabled = ‘true'”
Exchange must be part of the domain which you’re using in your lab / Production environment. next we’ll be joining this machine to our domain using the following script:
First we’ll change the hostname, restart and then join the domain
Change Computer name:
Rename-Computer -NewName “Exch2019” -DomainCredential WIN-EPM2CRB5MN9\administrator –Restart
Join the domain
add-computer –domainname cloud-tech.net -Credential cloud-tech\administrator -restart –force
Since I am doing a lab test only, I will use the default C drive to install Exchange, but if you’d want to configure a second Drive please let me know and I will add that part as well.
Installing Prerequisites – Exchange 2019 on Windows 2019 Core
EX2019 will require 2012R2 AD FFL
Check out your windows Version first for compatibility

After installing prerequisites, Installing UCMA
For UCMA on Windows Core you need to get a certain UCMA customized in order to work with Windows 2019 core.
After Extracting and copying the file to the C root drive
The setup file is called Ironmansetup.exe
After the Installation of UCMA, there will be another requirement,
Visual C++ Redistributable Packages for Visual Studio 2013
.\setup.exe /InstallWindowsComponents /CustomerFeedbackEnabled:False /LogFolderPath:C:\Logs\db4 /DbFilePath:C:\Mailbox\Database01\Database01.edb /MdbName:Database01 /DisableAMFiltering /IAcceptExchangeServerLicenseTerms /roles:mb,mt
I will be upgrading this with the latest Windows 2019 releases since this installation was done with Microsoft Windows 2019 Preview edition
