Trying to access Outlook Web Access (OWA) – IIS Application Pool MSExchangeServicesAppPool crash

If you try to access the OWA, the IIS Application Pool MSExchangeServicesAppPool crash and stop working.

To solve this issue, open the web.config from the virtual directory and change the following value:

<identity impersonate="True" /> back to: <identity impersonate="true" />

to

<identity impersonate="True" /> back to: <identity impersonate="false" />

Restart the Application Pool and OWA will work fine.
