Exchange Management Shell fails to load after Exchange SE update KB5071876

 

Hello,
After installing Exchange Server Subscription Edition update KB5071876, Exchange Management Shell no longer loads correctly and generates PowerShell related errors. The server is currently in maintenance mode.
I tested uninstalling and reinstalling the update, but the issue persists.
I verified the applied Group Policies and did not find any GPO explicitly blocking PowerShell script execution. I have attached screenshots of the error messages, the applied GPO settings, and the PowerShell execution policy output.
PowerShell execution policy result:
MachinePolicy Undefined, UserPolicy Undefined, Process Undefined, CurrentUser Undefined, LocalMachine RemoteSigned.
Despite this configuration, Exchange PowerShell scripts such as RemoteExchange.ps1, CommonConnectFunctions.ps1 and ps1xml files are still blocked and Exchange cmdlets are not available.
Any guidance or similar experience after installing this update would be greatly appreciated.
Thank you in advance.

  • Hey man, I cant see any screenshots, could you add them?

    On top of that: You can use the normal PowerShell and import the exchange management module as a workaround. 

    Add-PSSnapin Microsoft.Exchange.Management.PowerShell.SnapIn
