I have an email in Outlook 2003 which I am unable to delete. No virus, no spyware on this machine. We run Outlook 2003 as client with Exchange 2003 being our email server.
When I open the email, I get the message "could not open one of more attachments", then the email opens and there is no attachment. Then if I try to delete the message I get "unknown error" message.
The email was a delivery failure notification for a non-existent user on our domain.
Any idea how to get rid of this? It's very annoying.
