Comments about Kopano as a Alternative to Microsoft Exchange Server
Free and open source, and has most of the things you want from Exchange, including shared calendars.0
Scalable, open source with a great UX and it has all the features I need0
Stable and cheap backend, flexible frontend support, open source, in full control of your data0
OpenSource, better to maintain, "not Microsoft"-1
I tried a lot of MS alternatives, OX, Zimbra, Zentyal, but what fits most with Outlook Sync was the new Kopano, it's more flexible. You can use the web app or desktop app too.-1
Zentyal is a native Microsoft Active Directory implementation on Linux incorporating all the network services required in a small and medium business environment: Directory & Domain Server, Mail Server, Gateway and Infrastructure Server.
Comments about Zentyal as a Alternative to Microsoft Exchange Server
Not an Exchange alternative at all. Does basic AD but that is about it. It is more of a gateway server.0
While the comments below suggest that this is AD, not exchange replacement. It was supposed to ship with SoGo / openchange as a managed add-on. You also strangely enough can't have exchange without AD. but guests do keep on posting. Exchange is just an Add-On to AD. (It extends the schema).-1
They do not share any common functionality. Zentyal is an Active Directory substitute, Microsoft Exchange is a groupware E-Mail (enterprise grade) server.-2
No Exchange alternative and no support for MS Outlook Client7
