If I remember correctly, you need to set up a shared namespace in 
Dovecot. Something like this,

namespace {
   type = shared
   separator = /
   prefix = shared/%%u/
   location = 
maildir:/path/to/mail/%%d/%%n/mail:INDEX=/path/to/mail/%d/%u/shared/%%u/
   subscriptions = yes
   list = children
}
