Please describe the installation steps...  paths used etc.

Did this ever work?

Is the path listed in the event 'correct' ?

It was working before. Suddenly just started seeing that error.

Did you install anything else on the CAS, especially something that uses the EWS Managed API?

    <Data>Could not load file or assembly 'Symantec.EnterpriseVault.Owa, Version=10.0.1.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. Access is denied.</Data>

so the owa app pool id can not access the clientAccess\owa\bin directory to load Symantec.EnterpriseVault.Owa.dll

also should it be in the IIS APPPOOL\DefaultAppPool? i.e usually MSExchangeOWAAppPool
