I got into work today and noticed that no one can log into exchange via OWA. I started checking error logs on my store servers and found them all littered with these error messages;
Source: System.ServiceModel 4.0.0.0
Event ID: 3
Task Category: WebHost
User: System
WebHost failed to process a request.Sender Information: System.ServiceModel.ServiceHostingEnvironment+HostingManager/12547953
Exception: System.ServiceModel.ServiceActivationException: The service '/owa/service.svc' cannot be activated due to an exception during compilation. The exception message is: The authentication schemes configured on the host ('IntegratedWindowsAuthentication, Basic') do not allow those configured on the binding 'WebHttpBinding' ('Anonymous'). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly. Additionally, this may be resolved by changing the authentication schemes for this application through the IIS management tool, through the ServiceHost.Authentication.AuthenticationSchemes property, in the application configuration file at the <serviceAuthenticationManager> element, by updating the ClientCredentialType property on the binding, or by adjusting the AuthenticationScheme property on the HttpTransportBindingElement.. ---> System.NotSupportedException: The authentication schemes configured on the host ('IntegratedWindowsAuthentication, Basic') do not allow those configured on the binding 'WebHttpBinding' ('Anonymous').

Everything was working great on Friday and my error logs were unfortunately over written due to the amount of errors in my logs. Let me know if anyone has a fix for this or anything in the event log jumps out at you. All of the servers are set up the same (Server2012, 3 exchange 2013 store servers and 3 cas servers)
Thank you for all your help!
