quota corruption

[Erol YILDIZ]

When I first saw this problem I was suspicious about an outlook bug but when 
I saw that there are more than one users having the same problem I changed 
my mind because we are using cyrus on sles9 for nearly 4 years and we didnt 
have such problems. But anyway I will check the mailboxes with a different 
mail client. I am also thinking about disabling quota for all users for a 
short time just to solve the problem until I setup a mor recent version of 
cyrus on a different server. Is there a way to disable quota for all users 
with a single step?

Thanks
