How can I create a Search folder that contains multiple object types in Outlook 2007 from a secondary mailbox?

Question

I added an additional mailbox to my account. I want to create a view that is similar to the 'to do list' view that exists for that user. This means I want a search folder that searches that mailbox for objects of any type that have a follow up flag set or is a task.

You cannot do this from the UI. I found this:

Sub CreateNewSearchFolder()
   Set MyOutlookApplication = Outlook.Application
   SearchSubFolders = True
   Set MapiNamespace = Application.GetNamespace("MAPI")
   Set TasksFolder =     MapiNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderTasks).Parent
   strS = "'" & TasksFolder.FolderPath & "'"

   'strS = "'\\Mailbox - Other'"
   Dim folderName As String
   folderName = InputBox("Name of new search folder?:", "Folder Name", "")
   Dim objSch As Search

   Dim taskFilter As String
   taskFilter = "(""http://schemas.microsoft.com/mapi/proptag/0x0e05001f""= 'Tasks' AND     ""http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/81010003"" <>    2) OR (NOT(""http://schemas.microsoft.com/mapi/proptag/0×10900003"" IS NULL) AND ""http://schemas.microsoft.com/mapi/id/{00062003-0000-0000-C000-000000000046}/81010003"" <> 2)"
   Dim strTag As String
   strTag = "RecurSearch"


   Dim fupFilter As String
   fupFilter = "(NOT(""urn:schemas:httpmail:messageflag"" IS NULL))"


   Set objSch = Application.AdvancedSearch(Scope:=strS, _
   Filter:=taskFilter & " OR " + fupFilter + "", _
  SearchSubFolders:=True, Tag:=strTag)
   objSch.Save (folderName)

    End Sub

This works perfectly - for my mailbox. That is, it creates a view similar to the to-do list view that I want. It has every object type with a follow up flag, and tasks. However, if i uncomment the strS = "'\\Mailbox - Other'" line and run it, Outlook crashes on the .Save() line.

Any advice?
