I think this gets closer. It came from Sue Mosher's outstanding Microsoft Outlook 2007 Programming: Jumpstart for Power Users and Administrators. I hope she doesn't mind.

Sub ShowOtherUserCalFolders()
    Dim objOL As Outlook.Application
    Dim objNS As Outlook.NameSpace
    Dim objExpCal As Outlook.Explorer
    Dim objNavMod As Outlook.CalendarModule
    Dim objNavGroup As Outlook.NavigationGroup
    Dim objNavFolder As Outlook.NavigationFolder
    Dim objFolder As Outlook.Folder
    Dim colExpl As Outlook.Explorers
    Dim objExpl As Outlook.Explorer
    Set objOL = Application
    Set objNS = objOL.Session
    Set colExpl = objOL.Explorers
    Set objExpCal = _
      objNS.GetDefaultFolder(olFolderCalendar).GetExplorer
    Set objNavMod = objExpCal.NavigationPane.Modules. _
      GetNavigationModule(olModuleCalendar)
    Set objNavGroup = objNavMod.NavigationGroups. _
      GetDefaultNavigationGroup(olPeopleFoldersGroup)
    For Each objNavFolder In objNavGroup.NavigationFolders
        Set objFolder = objNavFolder.Folder
        Set objExpl = _
          colExpl.Add(objFolder, olFolderDisplayNormal)
        objExpl.Activate
        objExpl.WindowState = olMaximized
        objExpl.WindowState = olMinimized
    Next
    Set objOL = Nothing
    Set objNS = Nothing
    Set objNavMod = Nothing
    Set objNavGroup = Nothing
    Set objNavFolder = Nothing
    Set objFolder = Nothing
    Set colExpl = Nothing
    Set objExpl = Nothing
End Sub

Check out the returned values from the following code. It searches for a person by name, same way as when you are typing a recipient into a new email, and then grabs that persons shared calendar and enumerates all shared appointments.

Dim _namespace As Outlook.NameSpace
Dim _recipient As Outlook.Recipient
Dim calendarFolder As Outlook.Folder

Set _namespace = Application.GetNamespace("MAPI")
Set _recipient = _namespace.CreateRecipient(name)
_recipient.Resolve

If _recipient.Resolved Then
    Set calendarFolder = _namespace.GetSharedDefaultFolder(_recipient, olFolderCalendar)
    'This would display the calendar on the screen:
    'calendarFolder.Display

    Dim oItems As Outlook.Items
    Set oItems = calendarFolder.Items
    'oItems is now a set of all appointments in that person's calendar
    'Play on
End if

Just a suggestion to help people who may be trying to use the ShowOtherUserCalFolders() code posted here. This code will create multiple hidden instances of outlook which if run many times can eventual bog down your machine. Instead of creating a new Outlook.application you can call the current open one (outlook must be open for this to work).

To do this replace Dim objOL As Outlook.Application with Dim objOL as Object and Set objOL = Application with Set myOlApp = GetObject(, "Outlook.Application")

Also make sure you close the objExpCal Explorer as this will also create a hidden instance of outlook, add objExpCal.Close to the end of your code.
