Over the summer we upgraded our messenger system from 1.0.4 to 2.0.3. All went well, but it seems that since the client update the users are forced to have their personal history on the screen whenever messaging another user. In other words they see a history of all conversations to that user from previous sessions. Now onthe client side I can go in and turn off this history issue with Properties --> Options --> History --> unchecking Display history in conversation windows, but it has to be done on each station individually.

In C1, I see my MessengerService --> Policy Container --> Default Policy and can go to Policy --> Personal history and see that "Allow users to use Personal History" is unchecked but not locked. Shouldn't this be enough or do I have additional work to do to force turning off personal history to the clients?
