The options listed below can be used to customize the Web.config file on the CAS, which can typically be found in the directory:

• The name of the Version folder containing the Enterprise Vault resources that will be loaded during the Outlook Web Access (OWA) session, which is a sub-directory of 'OWA\EnterpriseVault\':
  
  <add key="EnterpriseVault_ResourceVersion" value = "v9.0.0.1193"/>
   
• The Folder where the diagnostic Log Files will be generated (Note the trailing slash):
  
  <add key="EnterpriseVault_LogFolder" value="C:\Program Files\Enterprise Vault\OWA 2007\logs\"/>

  <add key="EnterpriseVault_LogMailboxes" value="mailbox@mydomain.local;scndmbx@mydomain.local"/>
   
• When attempting to open an Item through OWA the original message must be restored from the Enterprise Vault Server, this key sets the number of times to check if an archived item has been restored (default 30):
  
  <add key="EnterpriseVault_RestoreWaitMaxIterations" value="30"/>
   
• The time to wait (milliseconds) between the previously mentioned checks for the restoration of the item (default 2000):
  
  <add key="EnterpriseVault_RestoreWaitSleepTime" value="2000"/>
   
• This determines the number of milliseconds the EV OWA extensions will wait until the http (or https) request times out (default 30000):
  
  <add key="EnterpriseVault_HttpWebRequestTimeout" value="30000"/>
   
• The URL to use when calling the Exchange Web Services on the CAS, (default "<https://localhost/ews/exchange.asmx>"):
  
  <add key="EnterpriseVault_ExchangeWebServicesUrl" value="https://localhost/ews/exchange.asmx"/>
