How Can I Use Word as My Default Email Editor in Microsoft Outlook?
You may want to use Word as your editor for email messages in Outlook because
of its advanced editing capabilities, the automatic language selection (my
favorite), or because you "simply" like it.
Keep in mind, though, that you should use plain text or
maybe HTML formatting unless you know the recipient also uses Outlook.
