Microsoft Dynamics – Selecting an Org

# These two functions are convenient for CRM admins to quickly gather a hosted organization object from on-premise Microsoft Dynamics.
# One function is to attempt to query the App server for a specific name.
# If no such records exist, then the second function would invoke to allow the user to select from a list of known Orgs.
