Also, do you have any ISA server to publish your OWA/RPC to the Internet ? Please give little more details on how your service is published. Creating EVS and folders underneath is very straight forward. But I need to understand your architecture to answer all your other questions. http://support.microsoft.com/default.aspx?scid=kb;en-us;326271 Refer the document in the above link. It talks about creating EVS and folders in a clustered BE environment in pages 33-37. However, the same basic concepts applies to standalone EVS too. This will give you and understanding of how EVS is created and configured. HTH Regards, Raj
