There is a language bug. Free/busy view seems to work only in english (US). I checked it in polish, german and english (UK) and it's buged. Doesn't show any free or busy time just non-working and when i get back to another view i can't see any appointments. I need to relog to see them again. Is there any solution for this?
I have the latest release of Zimbra 7.1.1 Open Source.
