Using MS Outlook 2002, I send mails to some people who sometimes would receive it (my mail) in Html format...and some other people would receive it with the body of my mail empty. I am sending my mails correctly

and that just happens from times to times.

What could be the problem.

I am behinde an enterprise MS Exchange server: people of the MS Exchange network are asking me to double-check my settings on my local computer...but there's nothing wrong I could find. Any idea of what could that be?
