failes to send mail after first in loop - vba

Question

Got a macro running through columns with mail addresses using most parts from Ron de Bruin.
The macro runs through just fine, but only sends the first hit in column B and doesn't display any of the other hits when i try to watch it? What could be the issue?
The code is so that I can get the default signature from outlook, thats why it's .Display first in the code.
Sub mail_HTML()
'For Tips see: http://www.rondebruin.nl/win/winmail/Outlook/tips.htm

Dim OutApp As Object
Dim OutMail As Object
Dim cell As Range
Dim strbody As String
Set OutApp = CreateObject("Outlook.Application")
Set OutMail = OutApp.CreateItem(0)
On Error GoTo cleanup
For Each cell In Columns("B").Cells.SpecialCells(xlCellTypeConstants)
If cell.Value Like "?*#?*.?*" And _
LCase(Cells(cell.Row, "C").Value) = "yes" Then
strbody = "<H3>Hei " & Cells(cell.Row, "E").Value & "</H3>" _
& "<p>" & Range("k4") & "<p>"
On Error Resume Next
With OutMail
.Display
.To = cell.Value
.Subject = Range("K12").Value
.HTMLBody = strbody & .HTMLBody
'You can add files also like this
'.Attachments.Add Range("O1").Value
.Send
End With
On Error GoTo 0
Set OutMail = Nothing
End If
Next cell
cleanup:
Set OutApp = Nothing
Application.ScreenUpdating = True
End Sub

Answer 1

When you set
Set OutMail = Nothing
You dont have any access to the object anymore (because it is destroyed). But you set it before the loop. You need to set it in every loop then like this:
On Error Resume Next
Set OutMail = OutApp.CreateItem(0)
With OutMail
.Display
.To = cell.Value
.Subject = Range("K12").Value
.HTMLBody = strbody & .HTMLBody
'You can add files also like this
'.Attachments.Add Range("O1").Value
.Send
End With
On Error GoTo 0
Set OutMail = Nothing
So after 1 Email the oject is destroyed, but you are not aware because of the on error resume next

Answer 2

Tried that but it is not working for me, here is my code:
Do Until in_file.EOF
Email_To = in_file!email_address
Email_Bcc = ""
Email_Body = in_file!email_salut & " " & in_file!email_name & ", test this."
Email_Subject = "Email Subject"
Set mail_object = CreateObject("Outlook.Application")
Set mail_single = mail_object.CreateItem(0)
With mail_single
.Subject = Email_Subject
.To = Email_To
.cc = Email_Cc
.BCC = Email_Bcc
.Body = Email_Body
.send
End With
Set mail_object = Nothing
Set mail_single = Nothing
in_file.MoveNext
Loop
