Experimente assim:

Private Sub Workbook_SheetChange(ByVal Sh As Object, ByVal Target As Range)
    Dim wsHist As Worksheet, Rng As Range
    Set wsHist = Sheets("História")
    If Sh Is wsHist Then Exit Sub
    Set Rng = wsHist.Range("A" & Rows.Count).End(xlUp).Offset(1)
    With Rng
        .Value = Now
        .Offset(, 1) = Sh.Name
        .Offset(, 2) = Target.Address
        .Offset(, 4) = Environ("UserName")
        If Target.Cells.Count > 1 Then
            .Offset(, 3) = "Valores Alterados"
        Else
            .Offset(, 3) = Target.Formula
        End If
    End With
End Sub

Muito Obrigado.
