The BBC reports on the changes to email and document handling that will be found in Office 2003:

"Forwarding is obviously the key issue," said Mr Pryke-Smith. "This puts control into the hands of the person sending the e-mail, as opposed to allowing the proliferation of messages." In Office 2003, people can limit who else can open, edit, copy or even print a document. The new look for Outlook you can even set a time limit on it, so that a document only be read for a set period and then become effectively locked. In any case, a copy will most likely remain on a central server.

I have no problem with this. To most Canadians Norwich Union makes them thing of the f'ing words: "Its Patrick...he just got life insurance". To me it also raises the specter of a stupid side of email - unrestricted forwarding. You see, Patrick's premiums went to paying out a settlement on a liable claim based on staff jabbering about a competator on supposedly internal emails. I have seen too many cases of accidental sharing or intentional stupidity causing breaches of privacy impossible in the world of filing cabinets. This will reinforce the rule - just because you can share does not mean you should.
