Users may receive the following error when access /EXCHANGE or /PUBLIC on an SBS 2008 server.  Users can still access OWA using the /OWA path. Note: SBS 2008 users should always use /OWA or RWW to access OWA.  This issue is a very rare issue, but if encountered can take a very long time to troubleshoot.
