vsto outlook ItemAdd event on a public folder on Exchange

Continuous googling did its job. I found how to resolve the issue. It appears I am not the only one who experience it.

I added the reference to Items collection of the folder I want to track to the global scope:

internal static class stor
{
    public static Outlook.Items i;
}

public partial class ThisAddIn
{
    internal static Outlook.Folder posts_folder = null;

    private void ThisAddIn_Startup(object sender, System.EventArgs e)
    {
        // the code for finding a posts_folder is omitted

        stor.i = posts_folder.Items;
        stor.i.ItemAdd += new Outlook.ItemsEvents_ItemAddEventHandler(Posts_Add);
    }

    static void Posts_Add(object Item)
    {
        System.Windows.Forms.MessageBox.Show("New item");
    }
{

Now it works as expected. Alhough I do not understand all the details they say it is a garbage collection issue. My event handler eventually was thrown into the garbage. The reference to the Items collection on the global scope prevents this from happening.
