Copy of attachment created

[Alanna Turco]

I've been using outlook for years but about a month ago, whenever I send an
email with an attachment, a copy is made and it sits in my outbox. It is an
email that is not addressed but has the same attachment in it. Any
suggestions on why this is happening and how to stop creating these extra
messages?

are you using any add-ins? what about rules on sent items? What type of
email account? What firewall, antivirus and antispam products are installed?
