Dim sh As Worksheet
Dim wb As Workbook
Dim FileExtStr As String
Dim FileFormatNum As Long
Dim TempFilePath As String
Dim TempFileName As String
Dim OutApp As Object
Dim OutMail As Object
Dim MailAdress As String


TempFilePath = Environ$("temp") & "\"


If Val(Application.Version) < 12 Then
'You use Excel 97-2003
FileExtStr = ".xls": FileFormatNum = -4143
Else
'You use Excel 2007
FileExtStr = ".xlsm": FileFormatNum = 52
End If


With Application
.ScreenUpdating = False
.EnableEvents = False
End With


Set OutApp = CreateObject("Outlook.Application")
OutApp.Session.Logon


For Each sh In ActiveWorkbook.Worksheets
MailAdress = ""
On Error Resume Next
MailAdress =
Application.WorksheetFunction.VLookup(Int(sh.Name) ,
Sheets("LookupTable").Range("A1:B500"), 2, False)
On Error GoTo 0
strbody = "Dear All" & vbNewLine & vbNewLine & _
