GetSharedDefaultFolder call from BASIC

I realize this is a pretty narrow problem so I apologize in advance, but if this is some type of bug then I want to report it.  Even so, nearly all people will not be affected by it.
So...
I want to look for a schedule conflict for an Outlook resource, in my case a conference room, before I send an Outlook meeting invitation.  I pass in the start and end times and look at the shared folder for any overlapping appointments.
The following code is only half way there, but I get an "10090 ActiveX Automation Error" when I make the call to the Outlook COM function GetSharedDefaultFolder.  THIS CODE WORKS FINE IN VBA so I'm really confused.  Plus, I have looked everywhere and cannot find a list of error codes this corelates to.  Is it from Outlook or the Neowise BASIC plugin?  I don't know.
 Dim OLns As NameSpace
 Dim OLapp As Outlook.Application
 Dim myFolder As MAPIFolder
 Dim myItems As Items
 Dim myAppointment As AppointmentItem
 Dim myRecipient As Recipient
 Dim startdate As String
 Dim enddate As String
 Dim result As String
 Dim n As Integer
 Dim res As Boolean
 Dim myFolders As Folders
 Dim myObject As Object
 startdate = "1/6/05 09:00"
 enddate = "1/6/05 18:00"
 Set OLapp = CreateObject( "Outlook.Application")
 Set OLns = OLapp.GetNamespace("MAPI")
 Set myRecipient = OLns.CreateRecipient("_7th Floor Conf") 'Change you resource you have
 myRecipient.Resolve
 res = myRecipient.Resolved
    Set myFolder = OLns.GetSharedDefaultFolder( myRecipient,olFolderCalendar)
    'The regular local call works fine.
    'Set myFolder = OLns.GetDefaultFolder(olFolderCalendar)
    Set myItems = myFolder.Items
    myItems.Sort "[Start]", False
 myItems.IncludeRecurrences = True
    Set myItems = myItems.Restrict("[Start] > '" & startdate & "' AND [Start] < '" & enddate & "'")
 myItems.IncludeRecurrences = True
 Set myAppointment = myItems.GetFirst
    Do Until myAppointment Is Nothing
  result = result & myAppointment.Organizer & " "
        Set myAppointment = myItems.GetNext
    Loop

The best I can figure out is that this is a security issue with Exchange.  So I think there is no bug in RoboTask or the BASIC plug-in.
I think to get around this, you have to lower the administrative security settings for Exchange to allow requests from a COM add-in.  This is not practical for me and likely not for others either.
Oh well.
