How to remove synchronized folders

[brontosaurus]

Hi All, here's the situation: A while back I set up my Redirector to sycnhronize a few sub-folders of my Inbox (I use MS Exchange server for email redirection), which worked fine. Now, I no longer need to synch those folders, so I've set the Redirector back to "Inbox Only". My question is, how do I remove the folders from my View Options on the Blackberry? Obviously, I'd prefer not to have to wipe the device. Thanks very much -- Bronto.
