Hello All,

I have basically developed ASP.Net web application which access the Exchange 2013 calendar by using MANAGED API.

For authentication I am using the ADAL library and I have registered native client application in Azure Active Directory. Everything works perfectly so long as I run the application on localhost. the problem arises when I am hosting my ASP.Net web application to Azure by the means of publishing where in I import publishing profile website created on Azure.

Following is the stack trace of it:

Server Error in '/' Application.

Error HRESULT E_FAIL has been returned from a call to a COM component.

[COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.]
   Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext.RunAsyncTask(Task`1 task) +89
