Call to action: Exchange 2007 and Windows 2003 support

The discovery URL (https://webapps.exchangelabs.nl/hosting/discovery) was working fine, so at least something was working.

Another thing that was clearly visible was that processor utilization regularly peaked to 100%, sometimes staying at 100% for a longer period of time:
