Expand/collapse folders in the Outlook navigation pane programmatically

Question

I am writing an add-in for Outlook using C#. Is there are way to programmatically expand and collapse folders in the Outlook 2007 folders navigation pane? Also, is there an event fired when a folder is expanded?

Answer 1

Outlook does not expose events that will allow you to expand or collapse the folders in the treeview. You may be able to do this using the Windows API.
