A selling point of early versions of Office was "wordmail" where, with the click of a button, an email header was added to the Word document or Excel file. All you need to do was address it and click the Send a Copy button and the document was sent in the body of a message, not as an attachment.
To enable it in Office 2010 applications, you need to customize the Quick Access toolbar (QAT) or Ribbon in Word and Excel. Note: The Send to mail recipient feature is on the Publisher 2010 Send menu, as Send Current Page, but was hidden in Word and Excel.
In Word or Excel's File, Options dialog, select Customize Ribbon or Quick Access Toolbar. Under Commands not in ribbon, find Send to Mail Recipient and Add it to the Ribbon or QAT. Exit the dialog and return to the Office application and the command is ready to use.
The steps are similar in Word 2007 and Excel 2007: open the customize QAT dialog, location the Send to Mail Recipient command and add it to the QAT.
