exporting tasks from shared inbox

Hi guys. I've created the following code which will export my tasks to excel:

[VBA]Sub export_tasks()


'DECLARE VARIABLES

Dim strReport As String
Dim olnameSpace As Outlook.NameSpace
Dim taskFolder As Outlook.MAPIFolder
Dim tasks As Outlook.Items
Dim tsk As Outlook.TaskItem
Dim objExcel As New Excel.Application
Dim exWb As Excel.Workbook
Dim sht As Excel.Worksheet

Dim strMyName As String
Dim x As Integer
Dim y As Integer

'REMOVE EXISTING DATA

Set exWb = objExcel.Workbooks.Open("c:\systems\tasks\task.xls")
exWb.Sheets("Sheet1").range("A1:H2500").Select
exWb.Sheets("Sheet1").range("A1:H250").ClearContents

'REFERENCE WORKBOOKS

Set olnameSpace = Application.GetNamespace("MAPI")
Set taskFolder = olnameSpace.GetDefaultFolder(olFolderTasks)
Set tasks = taskFolder.Items
strReport = ""

'CREATE THE HEADER

exWb.Sheets("Sheet1").Cells(1, 1) = "Subject"
exWb.Sheets("Sheet1").Cells(1, 2) = "Start Date"
exWb.Sheets("Sheet1").Cells(1, 3) = "Due Date"


y = 2
For x = 1 To tasks.Count
Set tsk = tasks.Item(x)

'FILL IN THE DATA

If Not tsk.Sensitivity = olPrivate Then

'Add the data

exWb.Sheets("Sheet1").Cells(y, 1) = tsk.Subject
exWb.Sheets("Sheet1").Cells(y, 2) = tsk.StartDate
exWb.Sheets("Sheet1").Cells(y, 3) = tsk.DueDate


y = y + 1

End If


Next x

'SAVE AND CLOSE

exWb.Save
exWb.Close


Set exWb = Nothing

End Sub
[/VBA]

I also have a shared mailbox, can anyone tell me how to export tasks from that? I thought having the code to do it already that it would be easy enough but i can't work it out.
