Hi, I am developing some code for outlook right now and the way I am detecting the application running is by doing: Marshal.GetActiveObject("Outlook.Application"); If I get a comexception then outlook is not running. The problem is that sometimes this catches a dying outlook instance and the rest of my code tries to execute against this non existent instance with all kind of errors. Is there any way to get the current instance and ensure that it was not in the middle of a closing process? Thanks, Federico
