Do you know what kind of messages are being sent? Could they be "Read
Receipts"? Check Tools - Options - Preferences - E-mail Options - Tracking
Options and look at the options at the bottom dealing with deciding how to
respond to requests for read receipts.

I’ve noticed that he OUTBOX sometimes has messages I did not intentionally
send. Evidently some setting in the computer is automatically sending
some
messages that I want to stop. I’ve searched TOOLS – OPTIONS and not find
the
method of stopping automatic sends. Does anyone know how I can stop
Outlook
2007 from sending e-mail without my permission?
