EWS refers to the functions of IIS on a CAS Server that are used by the Outlook client, this is separate to OWA. EWS handles Free/busy,OOO,OAB and RPC.

Right-clicking on the Outlook 2007 tray icon and choosing Test email Autoconfig tests general autodiscover connectivity. It does not test EWS.

The EMS command Test-OutlookWebServices tests EWS.

Usage is Test-OutlookWebServices -identity user|fl Example of correct output:

PS C:\\Program Files\\Microsoft\\Exchange Server\\Bin> Test-OutlookWebServices -identity
benjaming|fl
