Our company uses Exchange Server, and I have set up several other computers
so that their Contacts are shared - but within their Contacts folders there
are subfolders - how do I manage to see the folders and the contents?

I have "owner" or "Publishing Editor" permission on these folders - and one
of the items that permissions cover is "Create Subfolders"

In my Outlook, I see a list of Contacts in the left pane, at the bottom is
"Other Contacts" and the list of computers that have shared with me is there
- but I can't see any of the Subfolders.
