Hello,

  If I'm not mistaken this is an issue that has come up before.
As I quote :
When a folder is assigned a quota it becomes a quota root for all 
subfolders except those that have quotas defined and their children. 
Under Cyrus it is not possible to remove a quota root, and reassign the 
relevant subfolders to a parent quota root.

There is a proposed solution sometime back the rmquota patch that it is 
included in a number of different cyrus imap packages.

I think more relevant for this issue is  the deletamailbox patch (that 
is based on the rmquota patch). I quote :
Cyrus imap doesn't remove the quota from a folder when this folder is 
deleted except if the folder is user.X folder. There are some comments 
in Cyrus code about possible places where code can be inserted to deal 
with this situation.

  These patch however are not yet compatible with the delayed delete 
code since in UOA we are not using cyrus 2.3.x. However if you think 
that this is serious matter we are willing to work with you so that this 
patch can me merged to the mail cyrus tree.
