Thank you for your reply.

When I use https I get this error:

New-PSSession : [srvexc03.mydomain.local] Connecting to remote server srvexc03.mydomain.local failed with the following error message : The SSL connection cannot be established. Verify that the service on the remote host is 
properly configured to listen for HTTPS requests. Consult the logs and documentation for the WS-Management service running on the destination, most commonly IIS or WinRM. If the destination is the WinRM service, run the 
following command on the destination to analyze and configure the WinRM service: "winrm quickconfig -transport:https". For more information, see the about_Remote_Troubleshooting Help topic.

 and when I use http, I get this one:

New-PSSession : [srvexc03.mydomain.local] Connecting to remote server srvexc03.mydomain.local failed with the following error message : The WinRM client cannot process the request. It cannot determine the content type of

Hi jamelbouzidi 

 

Did you use the SessionOption to skip the Certificate Checks?

 

Check your Exchange Konfiguration
Get-PowerShellVirtualDirectory -Server srvexc03 | fl

 

Regards

Andres

      No Authentication Protocol is active on the PowerShell Directory
      Set-PowerShellVirtualDirectory -Server srvexc03 -BasicAuthentication $true -WindowsAuthentication $true

        I fix then Authentification Protocol,

ExternalUrl                     : https://exc.mydomain.com/powershell

         But still doesn't work.

        I forgot to tell you that neither the OWA nor the ECP doesn't work, only when I enter https://127.0.0.1/ecp
