Exchanege 2013 - Powershell Remoting - WsIn

Hi Together

I have a following Problem...

I am trying to connect programaticaly to Exchange Server 2013 (Windows 2012) from another domain using

and Runspace to be able tu run powershell commands remotely.

The Problem is that i get message Access denied although i am connecting with Administrator account.

Error message i get:

Connecting to remote server failed with the following error message : Access is denied. For more
 information, see the about_Remote_Troubleshooting Help topic.
    + CategoryInfo          : OpenError: (System.Manageme....RemoteRunspace:RemoteRunspace) [], PSRemotingTransportException
    + FullyQualifiedErrorId : PSSessionOpenFailed

It seems to be a Problem with path of Powershell Virtual Directory in IIS.It Shows following directory path C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\PowerShell-Proxy.

As soon as i change the path to C:\Program Files\Microsoft\Exchange Server\V15\ClientAccess\PowerShell instead of Powershell-Proxy, which is actualy a valu on Exchange 2010 Version, everything is working fine and i am able to connect to Exchange and execute Exchange powershell commands.The Problem with this configuration is that if i change the path, Microsoft Exchange Powershell Console localy on Exchange Server does not work anymore.I get lot of Errors...

My IIS Configuration has Basic and Windows authentication enabled and winrm config is configured as follow:
