Hi Surendra Application_Error event can use to catching error either in log file or plain text file or store in db or email too. Step-1 global.asax void Application_Error(object sender EventArgs e) { var error = Server.GetLastError(); if (error.Message != Not Found) { // Send email here... } } Step-2 web.config set customErrors=Off Step-3 public class MvcApplication : System.Web.HttpApplication { public static void RegisterGlobalFilters(GlobalFilterCollection filters) { filters.Add(new HandleErrorAttribute()); // Must Remove this line } ... } Why Remove this line By default (when a new project is generated) an MVC application has some logic in the Global.asax.cs file. This logic is used for mapping routes and registering filters. By default it only registers one filter: a HandleErrorAttribute filter. When customErrors are on (or through remote requests when it is set to RemoteOnly) the HandleErrorAttribute tells MVC to look for an Error view and it never calls the Application_Error() method To get the ApplicationError() method called for every unhandled exception simple remove the line which registers the HandleErrorAttribute filter.
