This error occurs when Chronobis is not able to determine the URL for your Exchange folder under OWA.
This might occur if:
1) You are using Exchange / OWA 2007.
See
Exchange 2007 Users thread.
2) Your OWA Server has a non-standard HTML template or Chronobis is unable to parse the HTML.
You can set the
Override User URL setting in the configuration to attempt to bypass this error.
