Rev, as I just wrote in the OE spellchecker Threath, the spellchecker is an office shared feature, so it needs to be installed. When Outlook was installed probably all shared applications weren't installed. This features include but are not limited to Clipboard, Office Assistance, SpeelChecker, Dictionaries, Help menus, Filters and conversion tools, International Settings and other that I don't remember. It depends a lot in the Office version, but the speelchecker is not for Word only, it just install by default with Word
