Ahmet Bey orada ki işlemi yaptığım zaman ekranda bu sefer aşağıda ki hatayı alıyorum.

The WinRM client received and HTTP server error status (500), but the remote service did not include any other information about the cause of the failure. For more information, see the about_Remote_Troubleshooting Help topic.
It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true -CurrentVersion 'Version 14.1 (Build 218.15)".
