Shared task folders in OWA 2013

Hi,

is there any way with Exchange 2013 to access shared task folders in OWA?

I was able to share calendars using web app, but it seems that's it.

Then I thought about public folders and found the info that they aren't (yet?) supported in OWA. However it's kind of strange that you can control public folder access in Web App policies.

Are public folders supported in the meanwhile? If not, why can they be enabled or disabled in Web App policies?

Thank you!
