        OutlookInterop.NameSpace ns = app.GetNamespace("MAPI");

        OutlookInterop.MAPIFolder contactsFolder = app.ActiveExplorer().Session.GetDefaultFolder(OutlookInterop.OlDefaultFolders.olFolderContacts);

        foreach (OutlookInterop.MAPIFolder subFolder in contactsFolder.Folders)

        {

            if (subFolder.Name == "MAPI")

            {

                return true;

            }

            else

        }

        return false;

     }

    

  

    protected void Page_Load(object sender, EventArgs e)

            OutlookInterop.ContactItem newContact = (OutlookInterop.ContactItem)app.CreateItem(OutlookInterop.OlItemType.olContactItem);

            //    if (newContact.Display(true))

            //    {

            newContact.FirstName = (txtfirstname.Text);

            newContact.Display(true);

            //newContact.Save();

            //}

         

          

            

        }

        catch (Exception ex)
