Assembly: Microsoft.Office.Interop.UccApi (in microsoft.office.interop.uccapi.dll)
The events are used to notify an application of the response to an asynchronous request to send a message (SendMessage) in an instant messaging session. This is a dispinterface. Its members define the event handlers for the events raised by an IUccInstantMessagingSession object. To catch the events, a UCC API client must implement these event handlers and advise the event source of the implementation if it is interested in receiving the events. To prevent memory leaks, the client should unadvise the events when it is no longer interested in the events. The interface identifier (IID) of this interface is 6853A6B5-88FA-46D2-B5DA-758DAB4E0065.
