Security Update For Exchange Server 2016 CU23 (KB5019758)

https://www.microsoft.com/en-us/download/details.aspx?id=104727

After the Reboot i've checked the Mitigations. The Mitigation is still active.

."C:\Program Files\Microsoft\Exchange Server\V15\scripts\Get-Mitigations.ps1"

It's best practices to run the HealthChecker Script after the Installation of a CU or Security Update

As i have installed it already, i just run it to update. The Message is a bit wrong. You can't just rerun the command, you have to close the Exchange Management Shell and reopen it after the update

.\HealthChecker.ps1
