Hiding special folders in different MUAs

[Diego M. Vadell]

Hi,

   I started to use Kolab some months ago and I'm very happy with it. It 
has made a 300 users migration, basically, a non-issue. But (there is 
always something :) ) I would love to be able to hide the special 
folders (the ones where people gets their contacts, calendars and such).

The only thing I could find in the wiki was that it does work with Kontact

"Kolab and the Kontact client is setup by default to hide the use IMAP 
folders for other things besides e-mail. If needed, e-mail with these 
resources is automatically filtered when it arrives, never going to the 
e-mail Inbox."

but nothing about Outlook or thunderbird. So:

* Is there any way to hide them?
* Is there any way to configure them below a folder called ¨DO NOT 
TOUCH!" or something like that?

Thanks in advance,
 -- Diego.
