Since mid-2023, Exchange 2016 and Exchange 2019 do not need the MSMQ (Message Queuing) feature on the Windows Server anymore. You can de-install it via PowerShell (Run as Administrator):
Remove-WindowsFeature NET-WCF-MSMQ-Activation45,MSMQ
A server restart is needed after completion of the command.
Thanks for this - removed it from Windows Server 2019 as it is no longer required for Exchange 2019. Microsoft told me so.
