Sorry if this doesn't answer your question, but I think you need to use the right tool for the right job.
In column A : Names of the people
In column B : E-mail addresses
In column C:Z : Filenames like this C:\Data\Book2.xls (don't have to be Excel files)
The Macro will loop through each row in "Sheet1" and if there is a E-mail address in column B
and file name(s) in column C:Z it will create a mail with this information and send it.
Sub Send_Files()

Dim OutApp As Object
Dim OutMail As Object
Dim sh As Worksheet
Dim cell As Range
Dim FileCell As Range
Dim rng As Range
With Application
.EnableEvents = False
.ScreenUpdating = False
End With
Set sh = Sheets("Sheet1")
Set OutApp = CreateObject("Outlook.Application")
For Each cell In sh.Columns("B").Cells.SpecialCells(xlCellTypeConstants)
'Enter the path/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
.to = cell.Value
.Subject = "Testfile"
.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
.Send 'Or use .Display
End With
Set OutMail = Nothing
End If
Next cell
Set OutApp = Nothing
With Application
.EnableEvents = True
.ScreenUpdating = True
End With
End Sub
