I would do things differently. As I understand it from your code, you want to send a copy of each message you send to another e-mail address but with any attachments removed? That being the case
Code:
Private Sub Application_ItemSend(ByVal Item As Object, Cancel As Boolean)
Dim olCopy As MailItem
Dim olAtt As Attachment
Set olCopy = Item.Forward
With olCopy
For Each olAtt In olCopy.Attachments
olAtt.Delete
Next olAtt
.To = "someone@gmail.com"
.Send
End With
lbl_Exit:
Exit Sub
End Sub
should work.
