[Dovecot] Outlook can't see namespace folders

[James]

Hi guys i understand that you can't subscribe to the Prefix names of 
namespace folders right now with dovecot.
But for instance if i user outlook express and it can't see the prefix 
name then it can't see the subfolders of that "prefix folder" either.
So even though it can detect and see the subfolders it won't display 
them cause it can't see the "parent"

Is there any fix for this? it's also kind of annoying in thunderbird but 
at least you can still see the subfolders.

TIA
James

Here's my config

        log_timestamp = "%Y-%m-%d %H:%M:%S "

            passdb ldap {
                args = /etc/dovecot/dovecot-ldap.conf
            }
            userdb ldap {
                args = /etc/dovecot/dovecot-ldap.conf
            }
        }
