Hi All
I have made a new project as add ins for the outlook and add this code

using System;
using Microsoft.Office.Core;
using Extensibility;
using System.Runtime.InteropServices;
using Outlook;

namespace outlookintegration
{
 #region Read me for Add-in installation and setup information.
 // When run, the Add-in wizard prepared the registry for the Add-in.
 // At a later time, if the Add-in becomes unavailable for reasons such as:
 // 1) You moved this project to a computer other than which is was originally created on.
 // 2) You chose 'Yes' when presented with a message asking if you wish to remove the Add-in.
 // 3) Registry corruption.
 // you will need to re-register the Add-in by building the MyAddin21Setup project
 // by right clicking the project in the Solution Explorer, then choosing install.
 #endregion
