And yet again! I didn’t say that. I said for professional enterprise support you obviously need to pay - name me one comany that provide pro enterprise support for free?! (i.e. instantly telephone support, remote access support etc). You can’t expect instant answers for free. You posted about two hours ago - give people a chance to respond! It’s Community forum - most people are probably at work at this hour.
You said you wanted enterprise support - then you said you didn’t. And now you are again damanding instant answers to a problem you are having! You might have more luck if you stop trying to put words into people’s mouths, trying to shove your unusual opinion of what ‘supported’ means into everyone else and generally barging in like a bull in a china shop damanding people instantly help you for free!
In another genuine attempt to help you, if you want actual pro enterprise support and tested binaries (among other things like offical repository support etc), these are available for a fee. The free community edition is the latest code with the latest features and as a result sometimes there are bugs. The free community edition is used by many people and when they have problems, they politely post in here or the Zarafa forum and they get helped. Not always instantly and not always fully successful on the first try - there is no reason to expect that. Most people have no problems with it and it works as expected.
Please stop trying to tell everyone that because you are unable to get it to work it must mean it doesn’t work for anyone ever! If you can’t get any of the distributions working then it likely something you are doing, not a problem with the software.
In the end though, maybe Kopano isn’t what you are after. If that is the case, there is no need to be insulting about it. If you just tell everyone it is rubbish or not ready, don’t be too surprised if you don’t get instantly helped.
