Hello, Hoping someone can shed some light on the subject to me. In outlook 2003, when i right click->options, i can view the 'internet header' of a message. However, messages to myself do not contain any information in this section. Please advise, thanks,

If you are using Exchange 200x there are no headers because no SMTP server is used to process the email. It is written by the ESE database engine to your mailbox.
