In OUTLOOK 97 the problem is that when you hit 'reply', the default is to send in Rich Text format. I think the only way to stop this is to double click on the 'pic microcontroller discussion list' destination ( To... ) field _EVERY_ time you reply and unset the 'Always send to this recipient in Microsoft Exchange Rich Text format' checkbox.
