StoresEvents_12_Event.StoreAdd Event not firing when using Data File Management menu

[lgwapnitsky]

I am writing an Outlook add-in that needs to fire when a PST is added/removed. I have successfully fired the event using the AddStore and RemoveStore functions, as well as when I use the "Open -> Outlook Data File" menu option. The issue is that when I go through the Data File Management screen, the event never fires.

Here is the "dummy code" I'm using outside of my main application for testing purposes:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml.Linq;
using Outlook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;
using System.Windows.Forms;

namespace StoreTesting
{
    public partial class ThisAddIn
    {
        Outlook.Application olApp = new Outlook.ApplicationClass();
        
        Outlook.Stores stores;
        Outlook.Store store;

        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            stores = olApp.Session.Stores;
            stores.StoreAdd += new Outlook.StoresEvents_12_StoreAddEventHandler(stores_StoreAdd);
            stores.BeforeStoreRemove += new Outlook.StoresEvents_12_BeforeStoreRemoveEventHandler(stores_BeforeStoreRemove);
        }

        void stores_BeforeStoreRemove(Outlook.Store Store, ref bool Cancel)
        {
            MessageBox.Show("store removed");
        }

        void stores_StoreAdd(Outlook.Store Store)
        {
            MessageBox.Show("store added");
        }


        private void ThisAddIn_Shutdown(object sender, System.EventArgs e)
        {
        }

        #region VSTO generated code

        /// <summary>
        /// Required method for Designer support - do not modify
        /// the contents of this method with the code editor.
        /// </summary>
        private void InternalStartup()
        {
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }
        
        #endregion
    }
}

Any help would be greatly appreciated.

Thanks,
Larry
