I was digging a little bit deeper into the Recipient Management without Exchange Server. I've already blogged about it how to install the Managment Tools only fo install the Recipient Management PowerShell
Install and use Exchange 2019 CU12 Recipient Management PowerShell
As you can see on the Server the Exchange Server 2019 CU12 is installed (Management Tools only)
I found the References of the PowerShell Snapins in the Registry here:
I had a look at the DLL "Microsoft.Exchange.PowerShell.Configuration.dll" with ILSpy.
As you can see there are many dependencys to other DLL's in the C:\Program Files\Microsoft\Exchange Server\V15\Bin Directory
Then i have installed the Security Update from Mai 2022
Security Update For Exchange Server 2019 CU12 (KB5014261)
As you can see the Size did not change, but the Date and the Version Number did.
It's the same Version as in Installed Apps
There is no easy way to copy the PSSnapin out to another Computer.
And you still have to update and apply the Security Updates to that Management Server.
