I've installed the latest beta release of zcs 5.0 and am pleased that there is now a way to share mailbox folders, much like you could already do with calendars and address books. I believe I read somewhere that this functionality in version 5 was only for the web client. I do however, see these shared mailbox folders show up as an available folder to subscribe to when I connect to my account through an IMAP client like Thunderbird. I can subscribe to this folder just fine but never see the contents like I would expect. The fact that I see these folders in the list of available folders to subscribe to makes me wonder if that functionality might eventually be there in zcs. Can someone answer that for me - will subscribing to these shared folders from an IMAP client ever be possible in zcs?
