Request processing failed because the WinRM service cannot load data or event source: DLL=”%ExchangeInstallPath%Bin\Microsoft.Exchange.AuthorizationPlugin.dll”User Action
Please check if “%ExchangeInstallPath%Bin\Microsoft.Exchange.AuthorizationPlugin.dll” exists.Additional Data
Loading %ExchangeInstallPath%Bin\Microsoft.Exchange.AuthorizationPlugin.dll failed with error=”126″ (%%126).
This can occur when the Exchange server does not have an %ExchangeInstallPath% system variable set. To resolve the error manually add the missing system variable.
Make sure you include the trailing backslash in the path.
After adding the system variable restart the server. You should now be able to connect to the Exchange server with the management tools.
