I'm not expert in this area, but have not seen anything that can strip components from within Outlook. Maybe you just need Outlook Express? Thunderbird is great as well. When installing, just choose the minimum options that you need. Anything that is required but not selected will get installed as well. Word/WAB integration is sometimes used to pass data from one app to another (eg, resolve WAB names in a document) and I think it adds a couple of options for emailing documents from within Word.
