All previous versions of Microsoft Office provided a spell checker for Outlook Express. Office 2007 attempts to do this but only provides a French dictionary.(No English Spell Checker in OE.) Additionally the spell and grammar checkers in Word 2007 are a joke. Microsoft acknowledges these shortcomings but so far has refused to fix them. Until they do, it is my advice to stay with Office 2003 or what ever else works for you.
