"Short Date" not a valid NumberFormat in Excel.
However, It is valid when used with the Format function.

The "mm/dd/yy" NumberFormat is legitimate, but maybe it is being overridden
by the code that places the data in the column.
You might try altering when the numberformat is added to the column.

This code..from Access..
objXLSheet.Columns("I:I").NumberFormat = "Short Date"
...or..
objXLSheet.Columns("I:I").NumberFormat = "mm/dd/yy"
...opens in Excel as the date's number, IE 39462
Ideas please? TIA - Bob
