    <p>I am getting this error in production. Don't know what exactly causes this.</p> <pre><code>OnSubscriptionError : Microsoft.Exchange.WebServices.Data.ServiceResponseException: The specified subscription was not found. </code></pre> <p>Now i want to simulate the behavior in my <strong>dev environment</strong>. </p> <ul> <li><p>I have subscribed to event <code>Connection.OnSubscriptionError</code> and my event handler is <code>OnSubscriptionError</code>. Now I want to test the handler. For that purpose I want some way to trigger that event with which i ham having trouble with.</p></li> <li><p>I have tried shutting down the exchange host service while the application is running , but that doesn't fire the <code>OnsubscriptionError Event</code>. </p></li> <li><p>I wanted to know whether the following code works when <code>OnsubscriptionError event</code> is fired. Or do i have to recreate the Subscription object before creating the connection. </p></li> </ul> <p><strong>Here is the sample code:</strong></p> <pre><code>Subscription =_exchangeService.SubscribeToStreamingNotifications( new FolderId[] { WellKnownFolderName.Inbox }, EventType.NewMail); CreateStreamingSubscription(_exchangeService, Subscription); private void CreateStreamingSubscription(ExchangeService service, StreamingSubscription subscription) { // public StreamingSubscriptionConnection(ExchangeService service, int lifetime) lifetime is in minutes and 30 mins is the maximum time till which // the connection can be open. Connection = new StreamingSubscriptionConnection(service, 30); Connection.AddSubscription(subscription); Connection.OnNotificationEvent += OnNotificationEvent; Connection.OnSubscriptionError += OnSubscriptionError; Connection.OnDisconnect += OnDisconnect; Connection.Open(); } private void OnSubscriptionError(object sender, SubscriptionErrorEventArgs args) { if (args.Exception is ServiceResponseException) { var exception = args.Exception as ServiceResponseException; } else if (args.Exception !=null) { Logwriter.LogMsg(_clientInfo.LogId, LogLevel.FATAL, "OnSubscriptionError() : " + args.Exception.Message + " Stack Trace : " + args.Exception.StackTrace + " Inner Exception : " + args.Exception.InnerException); } try { Connection = (StreamingSubscriptionConnection)sender; if(!Connection.IsOpen) Connection.Open(); } catch (ServiceResponseException exception) { } catch (Exception ex) { } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
