Sorry, I kind of assumed that you, as a regular (as far as I can tell from
my short time here) would know this - and it does say so in the referenced
article!

No it's not set by default. You could still use the same method by changing
the code to use late binding:

Sub SendDocumentInMail()

Dim bStarted As Boolean
Dim oOutlookApp As Object 'Outlook.Application
Dim oItem As Object 'Outlook.MailItem

On Error Resume Next

'Get Outlook if it's running
Set oOutlookApp = GetObject(, "Outlook.Application")
If Err <> 0 Then
   'Outlook wasn't running, start it from code
   Set oOutlookApp = CreateObject("Outlook.Application")
   bStarted = True
End If

'Create a new mailitem
Set oItem = oOutlookApp.CreateItem(0) ' olMailItem

With oItem
   'Set the recipient for the new email
  .To = "recipient@mail.com"
   'Set the recipient for a copy
   .cc = "recipient2@mail.com"
   'Set the subject
   .Subject = "New subject"
   'The content of the document is used as the body for the email
   .Body = ActiveDocument.Content
   .Send
End With

If bStarted Then
   'If we started Outlook from code, then close it
   oOutlookApp.Quit
End If

'Clean up
Set oItem = Nothing
Set oOutlookApp = Nothing

End Sub
