BES Messages folder is empty

Recently one of my users has found that the messages folder for BES e-mail (Exchange) is now empty. She has the standard catch all Messages folder, as well as a separate internet email folder that works just fine, but since she changed a theme on the Blackberry the BES message folder comes up empty, * No Messages*. (Selecting "view folder" from within BES Messages still shows all of the current messages from the exchange mailbox)

This worked previously, but seemed to "break" when the theme was changed.

How can I set this back so that the BES messages can be viewed from this folder?

This is a 8830 Sprint Blackberry with three message folders set up: BES account, personal email, and the catch-all Messages.
