Change Outlook Fields using group policies

[armatage]

For a reason that I won't go into we need to change everyone's outlook at work to show the field SENT instead of RECEIVED. I don't want to go to every user and change this and I don't want to rely on the users to set this so is there a way to change this using group policies? I've had a good look through the outlook settings in group policies but can't see any way of doing this.

We are using Office 2007.

Thanks
