Outlook problem, please help.

Seem to be getting a really annoying problem at work. I don’t have any rules or setting enabled to send back delivery receipt in Outlook 2003 when respondents read my messages but every now and again I seem to be getting them. The IT guys at work have had a look and can’t see why I’m getting these, there have also reinstalled Outlook and given me a new outlook profile but I still randomly get these delivery receipts. Any tips or pointers on what to do about it?

Thanks

Just to confirm, you are doing this: Tools--Options--E-Mail Options--Tracking Options.

Thanks kimsland for your reply.

Yes that is what my screen looks like but is that for when i open a message that has requested a read receipt from the sender?

Cause the problem i'm have is the other way round, I'm getting confirmation that xyz has read my email that i sent to them...

the strange thing is its totally random.
