Exchange Powershell cmdlets not accessible to Splunk for Exchange Powershell Modules?

Hi,

I've installed the Splunk App for Exchange and it appears that none of the powershell modules are functioning correctly. I know that they are running, but none are returning data. On further analysis, it appears that the built in exchange modules cmdlets that are being called from the splunk powershell modules are not accessible. Any ideas on how to fix?
