    {
        if (item is ContactItem)
        {

Your event registrations are probably getting garbage collected. Make sure folder is declared as a private class member and you will also need to manage a private class member collection of ContactItems (List<ContactItem> or similar) to ensure AfterWrite event handlers are properly registered and not disposed of.

For reference, see this SO post which describes VSTO limitations with event handling and how to properly attach to Office events.
