Good site Sue, unfortunately I still get an error...

Error says:
'The SendUsing configuration value is invalid'

This is the line that causes the error:
objMessage.Send

The Object Model Guard pops up again if I change the line to this:
.Send

Below is my full code:
Sub Send_Files()
'Working in 2000-2007
   Dim OutApp As Object
   Dim OutMail As Object
   Dim sh As Worksheet
   Dim cell As Range, FileCell As Range, rng As Range

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


   Set sh = Sheets("Send Emails")


   Set OutApp = CreateObject("Outlook.Application")
   OutApp.Session.Logon
   
   Set objMessage = CreateObject("CDO.Message")
   'Set objMessage = CreateObject("CDO.Message")

   For Each cell In sh.Columns("B").Cells.SpecialCells(xlCellTypeConstants)



       'Enter the file names in the C:Z column in each row
       Set rng = sh.Cells(cell.Row, 1).Range("C1:Z1")



       If cell.Value Like "?*@?*.?*" And _
          Application.WorksheetFunction.CountA(rng) > 0 Then
           Set OutMail = OutApp.CreateItem(0)



           With OutMail
           objMessage.Subject = "Example CDO Message"
           objMessage.From = "ryguy7272@hotmail.com"
           objMessage.To = cell.Value
           objMessage.TextBody = "This is some sample message text."
           
               
               .To = cell.Value
               .Subject = "Sales Reps. Data"
               .Body = "Hi " & cell.Offset(0, -1).Value

               For Each FileCell In rng.SpecialCells(xlCellTypeConstants)
                   If Trim(FileCell) <> "" Then
                       If Dir(FileCell.Value) <> "" Then
                           .Attachments.Add FileCell.Value
                       End If
                   End If
               Next FileCell
               
             
           objMessage.Send

           End With

           Set OutMail = Nothing
       End If
   Next cell



   Set OutApp = Nothing
   Set objCDOMail = Nothing

   With Application
       .EnableEvents = True
       .ScreenUpdating = True
   End With
End Sub

I am receptive to ideas...

Thanks to all who looked.
