Exchange 2010 OWA Error: “The website cannot be displayed” page HTTP error 500.

ERROR: When you go to the OWA link internaly and externaly  https://exchange.conto.com/owa the link brings the logon screen fine, but as soon as i input my username and password.. i get a “The website cannot be displayed” page HTTP error 500.

Resolution: In Exchange 2010 a new service has been introduced to handle forms based authentication (FBA). The service name is Microsoft Exchange Forms-Based Authentication service, MSExchangeFBA for short. If this service is stopped and you have FBA enabled, the default on SBS, you will get an error 500 attempting to access OWA. So if you receive this error please verify that the MSExchangeFBA service is started as your first step.
