Email boxes - sort/order messages
 

My BIS provider had "something" wrong and my email addresses deleted from their configuration page. So I set up the email addresses again, and the BlackBerry 9800 device made 2 icon for the 2 boxes (so I can see separately the emails).

My problem is that the Messages folder contains all of the previous email messages before this "incident", but this previous messages not show under the separated email boxes. Now I only see the new messages separately.

Can I do something that I see the previous messages separately?
