Kopano vs Microsoft Exchange ServerKopano has scalable backend and can do full MAPI server and clientside. The Webapp and Deskapp has intuitive and modern UI/UX.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.Stable and cheap backend, flexible frontend support, open source, in full control of your dataScalable, open source with a great UX and it has all the features I needOpenSource, better to maintain, "not Microsoft"

Zentyal vs Microsoft Exchange ServerNo Exchange alternative and no support for MS Outlook ClientWhile 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).Not an Exchange alternative at all. Does basic AD but that is about it. It is more of a gateway server.They do not share any common functionality. Zentyal is an Active Directory substitute, Microsoft Exchange is a groupware E-Mail (enterprise grade) server.
