Thuderbird and MS Word

My wife has started using Thunderbird as her email client since the version of Outlook we have is not compatible with Vista. But she wants to continue using MS Word as her email editor. We have both looked around and cant seem to find where you can change it. Any help would be appreciated.

Thanks

Get Windows Live Mail would be my suggestion.
Better then Outlook…and free
