This topic explains how to retain categories assigned to messages that are sent from a mailbox that is on Microsoft Exchange Server 2007. 

When a user creates a new e-mail message using Microsoft Office Outlook and assigns categories to it, the categories are removed before the message is delivered to the recipients. The categories are present in the copy of the message that is stored in the sender's Sent Items folder, but the messages in the Inboxes of the recipients do not have any categories assigned.


By default, Exchange 2007 removes any categories assigned to messages before the messages are delivered to the recipients. If you want messages to retain the categories assigned by the senders, you must configure your organization to not clear the categories when they are processed by your Hub Transport servers.

Before You Begin

To perform this procedure, the account you use must be delegated the Exchange Organization Administrator role. For more information about permissions, delegating roles, and the rights that are required to administer Exchange 2007, see Permission Considerations.


To use the Exchange Management Shell to disable clearing categories from messages sent
  • Run the following command:

    Copy Code
    Set-TransportConfig -ClearCategories $False

For detailed syntax and parameter information, see the Set-TransportConfig reference topic.
