Can't delete old folders from before ALTNAMESPACE

[Lee]

Hey All,
One of our users has the following folders listed in his account:

user/joe/INBOX/A =D (\HasChildren)
user/joe/INBOX/A =D/Accounts (\HasNoChildren)

These folders don't exist because the were remnants of our mail system 
before we turned on ALTNAMESPACE. The problem is that when I try to 
delete the folder in cyradm or in outlook, cyrus just returns errors.

Any ideas?

Thanks,
Lee
