Access Get subfolder of shared folder meetings - ms-access

Question

I have the code below that should let me retrieve the meetings from a shared sub calendar, but it doesn't work.
If I only try to access the main shared calendar it works perfect, but not for the sub calendars..
could someone point me to the right way?
Public Sub getCalendarData(calendar_name As String, sDate As Date, eDate As Date, Optional recurItem As Boolean = True)
On Error GoTo ErrorHandler
Dim oOL As Outlook.Application
Dim oNS As Outlook.Folder
Dim oAppointments As Outlook.AppointmentItem
Dim oAppointmentItem As Outlook.AppointmentItem
Dim strFilter As String
Dim ItemsCal As Outlook.Items
Dim olFolder As Outlook.Folder
Dim fldCalendar As Outlook.Folder
Dim iCalendar As Integer
Dim nmsNameSpace As Outlook.Namespace
Dim objDummy As Outlook.MailItem
Dim objRecip As Outlook.Recipient
'Set objects
Set oOL = CreateObject("Outlook.Application")
Set nmsNameSpace = oOL.GetNamespace("MAPI")
Set objDummy = oOL.CreateItem(olMailItem)
Set objRecip = nmsNameSpace.CreateRecipient("shared calendar name")
objRecip.Resolve
'Set filter to grab items by date range
strFilter = "[Start] >= " _
& "'" & sDate & "'" _
& " AND [End] <= " _
& "'" & eDate & "'"
With ItemsCal
.Sort "[Start]"
.IncludeRecurrences = recurItem
End With
If objRecip.Resolved Then
On Error Resume Next
Set fldCalendar = nmsNameSpace.GetSharedDefaultFolder(objRecip, olFolderCalendar).Folders("sub_calendar_name")
If Not fldCalendar Is Nothing Then
Set ItemsCal = fldCalendar.Items
If Not ItemsCal Is Nothing Then
For Each oAppointmentItem In ItemsCal.Restrict(strFilter)
Set objItem = oAppointmentItem
With oAppointmentItem
iCalendar = getSegmentIDByName(calendar_name)
meeting_id = insertAppointment(iCalendar, .Start, .End, scrubData(.Subject), scrubData(.Location), Format(.Start, "Long Time"), .duration, .Body)
Call GetAttendeeList(meeting_id, objItem, .Recipients)
End With
Next
End If
End If
End If
'Garbage cleanup
Set oAppointmentItem = Nothing
Set oAppoinments = Nothing
Set oNS = Nothing
Set oOL = Nothing
Exit Sub
ErrorHandler:
'MsgBox "Error: " & Err & " | " & Error(Err)
'Whenever error occurs, skip to next
Resume Next
End Sub
The problem is that fldCalendar is always returning nothing and I don't know what is wrong..
Thank you!

Keep in mind that in the cached mode when you are accessing a default folder from another mailbox, you are not accessing the whole mailbox - the folder (but not its subfolders) is cached in your primary OST file.
You can add the whole mailbox as a delegate store (Advanced tab of the Exchange account properties dialog box) and then drill down to that folder from Store.RootFolder (where Store is retrieved from the Namespace.Stores collection).
If using Redemption is an option (I am its author), its version of RDOSession.GetSharedDefaultFolder (or RDOSession.GetSharedMailbox) returns a live folder (RDOFolder), not its cached version, so you will be able to access the subfolders.
