            I checked your code without an problem. So you need to track your error message of WindowsForm APP and confirm closed your Outlook. In general, you may getting the error about COM ID issue.



            Please refer to the following links:



            How to open Outlook new mail window c#



            Code:



            Outlook.Application oApp    = new Outlook.Application ();
            Outlook._MailItem oMailItem = (Outlook._MailItem)oApp.CreateItem ( Outlook.OlItemType.olMailItem );
            oMailItem.To = address;
            // body, bcc etc...
            oMailItem.Display ( true );


            Debug Error:



            new Outlook.Application() thorws error if Outlook app is running

            • Hi Simon, I've checked the link above and followed the dcomcnfg thingy and I cannot find outlook message attachment, so maybe not a COM problem? Aactually my code above, once I pressed the button, there will be a pop-up at my taskbar stating: Another program is using outlook. To disconnect program and exit outlook, click outlook icon and click exit now. In reality, I did not open and outlook and when I checked control panel, outlook is also not running.

            Try something like the following (off the top of my head):



            Outlook.Application oApp    = new Outlook.Application ();
            Outlook.Namespace ns = oApp.GetNamespace("MAPI");
            ns.Logon();
            Outlook.MAPIFolder inbox = ns.GetDEfaultFolder(olFolderInbox);
            if (oApp.Explorers.Count > 0)
            {
            Outlook.Explorer expl = oApp.Explorers[1];
            expl.CurrentFolder = inbox;
            }
            else
            {
            inbox.Display();
            }

                      Try something like the following (off the top of my head):



                      Outlook.Application oApp    = new Outlook.Application ();
                      Outlook.Namespace ns = oApp.GetNamespace("MAPI");
                      ns.Logon();
                      Outlook.MAPIFolder inbox = ns.GetDEfaultFolder(olFolderInbox);
                      if (oApp.Explorers.Count > 0)
                      {
                      Outlook.Explorer expl = oApp.Explorers[1];
                      expl.CurrentFolder = inbox;
                      }
                      else
                      {
                      inbox.Display();
                      }
