C# - Looking to capture an event when a store is added/removed in Outlook

I am writing an add-in that needs to log when a PST is added/removed via the "Data File Management" menu or through AddStore/RemoveStore. I have been having difficulty on finding documentation on how to capture these events.

Advice is greatly appreciated.

Thanks, Larry

EDIT: Here's my dummy code that's not working:

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.NameSpace ns;

        Outlook.Stores stores;
        int open;

        private void ThisAddIn_Startup(object sender, System.EventArgs e)
        {
            ns = olApp.GetNamespace("MAPI");


            stores = ns.Stores;
            open = 0;

            foreach (Outlook.MAPIFolder mf in stores.Session.Folders)
                if (mf.Store.IsDataFileStore)
                    open += 1;

            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)
        {

            string rf = string.Format("{0}:{1} was removed", Store.DisplayName);
            MessageBox.Show(rf);
            open -= 1;
        }

        void stores_StoreAdd(Outlook.Store Store)
        {
            Outlook.MAPIFolder mf = ns.Folders.GetLast();
            string af = string.Format("{0} was added", mf.Name);
            MessageBox.Show(af);
            open += 1;
        }

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

        #region VSTO generated code

        /// <summary>
        /// Required method for Designer support - do not modify

            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }

        #endregion
    }
}


Outlook Session object has 2 events for adding and removing pststore -

  1. StoreAdd
  2. BeforeStoreRemove

You can subscribe to these event to get the notofication whenever any pst is added or removed.


Like this:

...

    private void ThisAddInStartup(object sender, EventArgs e)
    {
        this.Application.Session.Stores.StoreAdd += StoreAddEventHandler;
        this.Application.Session.Stores.BeforeStoreRemove += BeforeStoreRemove;
    }

    private void StoreAddEventHandler(Store store)
    {
        if (store.IsDataFileStore)
        {
          //Do something.
        }
    }

    private void BeforeStoreRemove(Store store, ref bool cancel)
    {
        if (store.IsDataFileStore)
        {
            //Do something.
        }
    }

...
