Attachment.Delete fails for 2007

Question

In outlook 2007. This is only for the RTF format.

void Application_ItemSend(object Item, ref bool Cancel)
        {
            Outlook.MailItem mail = Item as Outlook.MailItem;
            mail.Save();
            Outlook.Attachments attachments = mail.Attachments as Outlook.Attachments;

            if (attachments != null)
            {
                int iTotalAttachments = attachments.Count;
                for (int i = iTotalAttachments; i > 0; i--)
                {
                    Outlook.Attachment attachment = attachments[i] as Outlook.Attachment;

                    // Need to make sure the attachment is not inline
                    if (attachment != null && attachment.Type != Outlook.OlAttachmentType.olOLE)
                    {
                        attachment.Delete();
                    }
                }
            }
        }

However, if I attach multiple attachments. Typically for the second attachment - I get a message "The operation Failed".

This is happening for 2007. Not for 2010 and 2013. instead of attachment.Delete() mail.Attachments.Remove(i);

However the following code works on 2007On 2010 and 2013, it doesn't do a proper removal for the attachment (you can see the icon in the email body) ?

Answer 1

Do you get an exception only in the ItemSend event handler? I'd suggest using another place for such code.
