In my WSS Document Library EventHandler when I try to read outlook .msg file I am getting an error . "Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80080005." The error occuring in the line "Microsoft.Office.Interop.Outlook._Application outlook = new Microsoft.Office.Interop.Outlook.ApplicationClass();" How can I solve the error.
