Add Remove Message Inbox Headings

[Giulio Severini]

Hi

I have to do the ECDL (European Computer Driving License) Module 7
this week and I'm stuck on two points:

7.6.3.1 - Add/Remove Message Inbox Headings like: sender, subject,
date, received - How do I add or remove those headings in Outlook
2007?

Thanks for any help

Giulio.
