Turn off update links using VBA

Hi Experts,

I'm having trouble turning off the dialog box for user to choose update/edit the links in a Excel workbook using VBA. The codes are written in Access:

The prompt still appears although I set it as update always.
Can anyone help?
Thanks.

Dim acExcel, wb
     Dim xlPath
     xlPath = "F:\xxxxxx"
     Set acExcel = CreateObject("Excel.Application")
     acExcel.Visible = True
     Set wb = acExcel.Workbooks.Open(Filename:=xlPath, UpdateLinks:=xlUpdateLinksAlways)
     With wb.worksheets("Sheet1")
     '--------work on the data-------------
     End With
     wb.Close False
     Set wb = Nothing
     acExcel.Quit
     Set acExcel = Nothing

Select allOpen in new window
