Prevent users from saving instant messaging conversations

On BlackBerry devices that are running BlackBerry Device Software version 4.2 or later and the latest version of a collaboration client, users can save their instant messaging conversations as .txt files in the internal memory of their BlackBerry devices or on an external memory device. You can turn off this feature if you do not want users to save their instant messaging conversations on their BlackBerry devices.
In the IT policy for a group or user account, in the Instant Messaging policy group, change the Disable Saving Conversation IT policy rule to Yes.
