WARNING:  The Get-ClientAccessServer cmdlet will be removed in a future version of Exchange. Use the
Get-ClientAccessService cmdlet instead. If you have any scripts that use the Get-ClientAccessServer cmdlet, update them
 to use the Get-ClientAccessService cmdlet.  For more information, see http://go.microsoft.com/fwlink/p/?LinkId=254711.
