A solution that has worked for me when tackling this issue is to have the Excel File where the Import / Export is being executed open when the Import & Export is happening.

Some sample code examples below to highlight what works and what doesn't with VBA:

FAILS

wbTarget.SaveAs strFilename, xlExcel8
wbTarget.Close    
ExportSheetToDB strFilename, strSheetName, "tblTemp"

WORKS

wbTarget.SaveAs strFilename, xlExcel8
ExportSheetToDB strFilename, strSheetName, "tblTemp"
wbTarget.Close
