alternate namespace subfolders

[Russell]

Hi,   Now, I know that its been said before that we can't have subfolders from the inbox when using alternate namespace - but I'd be ever so chuffed if we could. Why? Simply because Microsoft Exchange lets you have an IMAP account where you can make folders at any level - within Inbox, or at the same level - and that's just what users are used to. Is this really an impossibility, or quite simply not implemented yet as no-one has seen a need for it?   I do so hate it when users ask why they can't do something....   Thanks!
