Allow Exchange 2013 to accept remote powershell from Orchestrator

Scenario: Orchestrator was not able to connect and run Exchange powershell commands. The error received is:
Error opening remote PowerShell runspace to endpointhttp://exchangeservername/powershell: Connecting to remote server failed with the following error message : The WinRM client cannot process the request.
1. Make sure the Execution Policy on the Exchange Shell is set to RemoteSigned.
a. Use Get-ExecutionPolicy to see what it is.
b. Use Set-ExecutionPolicy RemoteSigned to set it.
2. Enable Basic and Windows Authentication on the Powershell IIS Site.
a. Expand: Default Web siteàPowershell.
