I tried adding this code from:
http://blogs.msdn.com/dancre/archive/2004/03/21/93712.aspx
It breaks on this line: private CommandBarButton toolbarButton;
namespace outlook_add
{
using System;
using Microsoft.Office.Core;
using Extensibility;
using System.Runtime.InteropServices;
#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.
