I wrote this for Panda Restaurants who asked me to release it to the SolarWinds content exchange. We were having issues with some of the out of the box Exchange 2010 templates working with their Exchange 2010 environment, specifically those using PowerShell.
This still requires each server WSMAN (Windows Remote Management) to be configured but the script doesn't require the 'Execution Mode; Remote Host" but instead Local Host and Impersonation enabled. The user credential will need a higher level permission setting (I believe we're using Exchange Administrator (Read-Only) permissions).
Make sure you set your Trusted-Hosts correctly on both the SolarWinds server and the target servers as well as enable Windows Authentication for IIS service.
