Can't get Outlook.Application interop work in my MVC 4 project

I've been trying to use this interop in my MVC 4 project. I tried to make it simple just to get the idea. but I get an error "Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80010001 Call was rejected by callee. (Exception from HRESULT: 0x80010001 (RPC_E_CALL_REJECTED))."

Here's my simple code:

    using Outlook = Microsoft.Office.Interop.Outlook;
    [HttpPost]        
    public ActionResult SendEmail(SendEmailModel model)
    {
        if (ModelState.IsValid)
        {
            Outlook.Application app = new Outlook.Application();
            Outlook.NameSpace ns = app.GetNamespace("MAPI");
            ns.Logon("", "", Missing.Value, Missing.Value);


            Outlook.MailItem mailItem = (Outlook.MailItem)app.CreateItem(Outlook.OlItemType.olMailItem);

            mailItem.To = model.To;
            mailItem.Subject = model.Subject;
            mailItem.Body = model.Message;

            ((Outlook.MailItem)mailItem).Send();

            app = null;
            ns = null;

            return RedirectToAction("Index", "TechFile");
        }
        return View(model);
    }

Anyway I found Outlook redemption is an alternative way of doing this. but I don't know to get it started.

I resolved this by following this. http://support.microsoft.com/kb/329854
