"COM object that has been separated from its underlying RCW cannot be used" exception

1 Feb 2011 by Nish Nishant

One likely cause is that you are accessing a single threaded COM object from different threads. In your case, the event handler may not be running on the thread that created the COM object.

"COM object that has been separated from its underlying RCW cannot be used" exception

25 May 2016 by Sergey Aseev

You need have strong reference to event.Anything like thisMailItem mailItem;CloseEvent closeEvent;...InspectorEvents_10_Event inspectorEvents = mailItem.GetInspector;closeEvent = inspectorEvents.Close;closeEvent += delegate {.....};
