A mail server should not return an error immediately if it hits a lock  
IMO. It should at least wait some time and try again. Maybe it does,  
and maybe your server is simply too slow to handle such mailboxes.
Fact is, that Horde is accessing the server two times in a row  
quickly. Once when it loads the left menu, once when it loads the main  
view.
