Office has a feature called "Send to Mail Recipient" which puts the document in the message body, rather than attaching the document to the message. This is often referred to as "word mail" and while it sounds like a cool feature, reality is that few people had a need for it or used it and its not exposed on the menus in Office 2007.
The capability was not removed from Office and if you need it, you can add the Send to mail recipient to the Quick Access Toolbar (QAT).
From the Customize Quick Access Toolbar menu, More Commands dialog, choose All commands from the 'Choose Command from' dropdown and add the ”Send to mail recipient” command to the QAT.
