I am posting here because I am not sure which NG should get this and because
this NG seems to be fairly active.

A user emailed a Word 97 document to me. The attachment was over 3 MB. If
I save the attachment to my PC it stays the same size, but if I open it in
Word 2002 and then Save As, the file size changes to 25 KB. Is there any
explanation for this behavior? Why would his file be so large, it was a
simple 2 page letter?

My main concern is this: If he emails such documents to customers with
dial-up connections they could be very unhappy with us.
