This topic provides information about how to remove Read access from a message classification. Read permissions that are removed from the message classification object don't control whether the sender can use the message classification. They only control whether the message classification is displayed in the Permission menu in Microsoft Office Outlook Web App and Outlook 2007. Outlook Web App and Outlook 2007 users can send message classifications even if the user doesn't have Read access to the message classification.

For more information about message classifications, see Understanding Message Classifications.

Caution:
Before you modify message classifications in your production environment, we recommend that you use a test environment to understand how message classifications work. Before you modify message classifications, test them in a production environment.
