Just upgraded to Office 2007 (Outlook, Word, Excel, Power Pt ) Windows XP
... what does it mean it uses Word as editor? Just Spelling,
auto-correct, spacing? What else does Outlook use Word for?

Outlook versions prior to 2007 allowed the user to choose between using the
new-mail editor embedded in Outlook or to use Word as the new-mail editor.
Outlook 2007 only uses Word for its new-mail editor. A stub of Word is
included in the install of Outlook (unless, of course, you also install
Word as part of MS Office).
