Some of the users on our network have Outlook 2003 and others have Outlook 2007 (we are in the process of upgrading all to 2007)

We have a public folder on our Exchange Server with over 8,000 contact records. I have a number of goals and the advice I've found so far isn't comprehensive:
* modify to new record screen to include a an existing field not currently on the screen
* customize the Master Categories List and restrict viewers/data inputters to that list for future new records
* apply the changes (additional field and restricted categories) to all 8,000 existing records

Any help would be much appreciated.
