Access to Excel Error

[bhusiva]

an import is done from access to excel using docmd.transfersheet

DoCmd.TransferSpreadsheet 1, 8, "dbo." & QuerySending, SavedName, True, "InputRange"

In ADP the error displayed is runtime error 3274 and in ade it displays "The file is not in recognizable format"

This happens for only one user.
