Public folder doesn't appear in Outlook 2013-2010

Hello,

I have strange problem with my fresh Exchange 2013 Multi-tenant setup (Cu1), the public folder doesn't appear in Outlook 2013 and Outlook 2010 (not a problem with Ctrl+6) but I can see it in Outlook 2007 and with OWA perfectly. I use autodiscover and testexchangeconnectivity.com tell me that all my config is all-right.

Help will be much appreciate !

Thanks.
