When users launch an Outlook profile that has Business Contact Manager associated with it , they notice duplicate folders for Business Contact Manager in the Navigation pane.
Note : Closing and re-launching Outlook or removing and re-adding Business Contact Manager from the Outlook profile doesn't resolve the issue
Corrupt view in the navigation pane .
We were able to resolve the issue by launching Outlook using the resetnavpane command line switch.The switch clears and regenerates the Navigation Pane for the current profile.
