EV OWA Extension Failed to get hidden settings: System.NullReferenceException: Object reference not set to an instance of an object.

EV v10 OWA Extension is installed on two Exchange 2007 sp3 servers with  both mailbox and CAS role in a resource forest. However, when we try to login to the OWA on a server (OWAExchange) to access the mailbox (mailbox@smtp.company.com) on the other server (MbxExchange), no EV buttons and toolbar is shown.

Turned on the OWA extension debug log shows that it could impersonate using the EV service account to load hidden settings of the mailbox. However, it failed to load the hidden settings with the error message:

Failed to get hidden settings: System.NullReferenceException: Object reference not set to an instance of an object.

Any hints on what this error is about?

Related web.config appSettings:

  <add key="EnterpriseVault_ResourceVersion" value="v10.0.4.1189"/>
  <add key="EnterpriseVault_VaultServiceAccountUPN" value="EVServiceAccount@upn.company.com"/>
  <add key="EnterpriseVault_ExchangeWebServicesUrl" value="http://localhost/ews/exchange.asmx"/>
  <add key="EnterpriseVault_LogEnabled" value="true"/>

The complete log is included below:

    On the CAS server you're running OWA on, can you log on and go to this address?
    http://localhost/ews/exchange.asmx

     

    Based on it contacting this URL:
    https://MbxExchange/exchange/mailbox@smtp.company.com

    My best guess is that you only have https enabled on the server, and in the background you're getting an error saying that you should use SSL instead

    you could try changing this in your web.config, the same place where you enabled the logging

    <add key="EnterpriseVault_ExchangeWebServicesUrl" value="https://localhost/ews/exchange.asmx"/>

    What version of EV.  There were some fixes to OWA in the later releases so I would recommend you get to the latest EV 10 release and then retry.

    Also, please explain exactly isn't working.
