I have Lab environment with following servers. Exchange 2010 and EV 11.
Except OWA all other functions are working correctly.
when i log OWA can see only the shortcuts and not the complete message content. Also the EV buttons are not displayed either internally/externallly.
Follwoing things set from WEB.CONFIG
<add key="EnterpriseVault_LogEnabled" value="false" />
<add key="EnterpriseVault_ResourceVersion" value="v11.0.0.1351" />
<add key="EnterpriseVault_ExternalHostNames" value="owa.mail.com" />
<add key="EnterpriseVault_ExternalWebAppURL" value="/EnterpriseVault" />
<add key="EnterpriseVault_UseExternalWebAppUrl" value="true" />
<add key="EnterpriseVault_ExchangeWebServicesURL" value="https://localhost/ews/exchange.asmx" />
Also IP allowed set in EVAnon directory. OWA extensions installed on EXchange server . EVORT tool result success(all are green).
Followed http://www.symantec.com/business/support/index?page=content&id=HOWTO58375#v9666766 to set Data access account.
Anything else need to check?
