Remarks
The history property returns all the contents of the Office Communicator conversation window, including any error messages posted there. This property gives you the capability of archiving IM and conference conversation text. You cannot read this property in your event handler for the DMessengerEvents::OnIMWindowDestroyed event. The conversation history must be accessed to archive before the conversation window is closed.
Example
The example code reads the History property of the IMessengerConversationWnd interface object, imWindow, and displays the returned string on the application console window.
