Hi I've installed the patch to an Exchange 2016 server, the installation seemed to go fine and Exchange appears to is operating normally post reboot, however i've got an issue with a couple of 3rd party applications that connect to exchange via remote powershell and they are both broken.
One is our monitoring application called PRTG, and appears to be the same issue as mentioned by Googol.
I've enabled sensor debug logging and can see the following error message in the PRTG sensor logs.
2021-04-14 20:03:32,457 [DEBUG] - Running script: 'Get-ExchangeServer'
2021-04-14 20:03:32,490 [ERROR] - Error in RunRequest Get-ExchangeServer

Our other application that is also broken is an in house tool we use for Exchange admin tasks is producing a similar error message, the keywords are "System.Management.Automation.RemoteException: The syntax is not supported by this runspace. This can occur if the runspace is in no-language mode."
Any ideas?
