When I execute below code in console application it gives the accurate result but when I try it in windows form it throws COM exception on Outlook.Application app = new Outlook.Application();

The Exception is "Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80080005 
Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE))."

public static void ReadMail()
        {
            try
            {
               Outlook.Application myApp = new Outlook.Application();
               mapiNameSpace = myApp.GetNamespace("MAPI");
			   
			   ....some coding here...
			   
			 }
            catch (Exception ex)
            {
                
            }
			}

Do you know any solutions?
