Send mail using Outlook and .oft templates

There is already a page for sending mail using Outlook library.

Now this small code is a small tweak i.e. using Outlook Template (*.oft) file.

If you see the code there is hardly any complication but this exercise is time consuming as a whole.
It is because defining the different mail templates takes a lot of time from business POV.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using Outlook = Microsoft.Office.Interop.Outlook;

namespace emailTemplateTest
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                Outlook.Application otApp = new Outlook.Application();// create outlook object
                Outlook.NameSpace ns = otApp.Session;
                Outlook.Folder folder = otApp.Session.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderDrafts) as Outlook.Folder;
                Outlook.MailItem otMsg = otApp.CreateItemFromTemplate(@"d:\a2.oft", folder) as Outlook.MailItem;// Open the mail template
                Outlook.Inspector oInspector = otMsg.GetInspector;
                Outlook.Recipient otRecip = (Outlook.Recipient)otMsg.Recipients.Add("Temp@hotmail.com");
                if (otRecip.Resolve())// validate recipient address
                {
                    // Modify the body text as required
                    otMsg.Send(); // Send Mail
                    otRecip = null;
                    otMsg = null;
                    otApp.Quit();
                }
            }
            catch (Exception e)
            {
                Console.WriteLine("{0} Exception caught: ", e);
            }
        }
    }
}
