Issue that this update fixes

After you install update KB2817630, the Navigation pane (folder view) is not visible in Outlook. 

This issue occurs because a reference is matched to the wrong data structure. This causes the minimize button in the Navigation pane to be rendered at a size that is larger than expected. Therefore, the minimize button prevents the Navigation pane from being displayed.
