access to subfolders without read permission to inbox itself?

Is it possible to share inbox subfolders for Kopano users or groups without giving the permission to see mails in the inbox itself?

User xxx
  O  Inbox (not readable for neither group a nor user b)
    O  subfolder 1 (accessable for group a)
    O  subfolder 2 (accessable for user b)

Hello @onex-de,

via webapp you can set the permission to “others” and select “list folders” only for the root directory on user b and group a
and set the read/write permission on “subfolder 1” to "group a"
and read/write on “subfolder 2” to “user b”

should work

Unfortunatelly, it doesn’t … this was exactly the way, I tried before.
I set list folders via properties on “User xxx” and his inbox and set the other permissions to the subfolders.
When user zzz wants to open the shared mailbox of user xxx, the webapp throws an error, that user zzz has no access to user’s xxx mailbox.
