Apple targets Microsoft Exchange Server

Apple is leveraging the power of open source development in a new effort to directly target Microsoft Exchange Server. A new standards based, open source Calendar Server will debut this year with Leopard Server; the source itself is already available at,” Daniel Eran writes for RoughlyDrafted.

“Apple’s new Calendar Server is part of a new push into workgroup servers,” Eran writes. “Rather than trying to copy Microsoft’s tools, Apple is building its own
vision of collaborative workgroup services. Why Apple is offering a calendar server might come as a surprise.”

  1. We’ll see how effective this is in the next few years. VISTA is a new coat of paint on XP, but it includes a bunch of new “features” that a lot of Windows users will not be happy about (DRM, overbearing security).

    Apple is great at integrated solutions so I can see them making a compelling product, but how well they’ll sell remains to be seen.

  2. Nah… Microsoft Exchange is too entrenched & just too damn good. Apple’s piecemeal approach can never unseat Microsoft in the enterprise. Never. Let’s face it, folks… it just isn’t going to happen. That’s not a really horrible thing, though — Steve Jobs has his eye on the consumer, and he’s winning over the consumer. But he will NEVER EVER EVER win over the enterprise customers. It just isn’t going to happen in our lifetime or the next lifetime. Sorry. But consumers are where all the real fun is to be had!

  3. For a small company like us in France this sort of colllabrative tool built into Os X server will save us a bundle on our meagre IT budget. I know there are progs out there that share calendar data but take up some time in managing and are not centralised. I am the IT department, head chef, maintenance man etc etc and know there are plenty small companys that don’t want to spend all day managing their IT infrastructure… if they can do it with the address book as well I’ll be really happy.

  4. @ MacBill – …”It just isn’t going to happen in our lifetime or the next lifetime.”

    Well not to diss you but lets check out the figures here, the average life span for a person in the “Western world” at the end of the Twentieth Century is about 77 years – and i am going to round this number down to 70 years, and then add half that figure – to come up with 105 years.

    Apple are only 30 years old, and look what they have achieved so far in this nascent biz.

    The Wright Brothers made their first powered and controlled flight in 1903 and by 1969 man was walking on the moon – only sixty-six years later.

    So many many things are going to change, even by the end of my lifetime and I’m almost 48. The next 105 years will be so phenomenal, if not worrying, that my head spins thinking about it.

    The computer enterprise market is still a glint in the consumers eyes.

    Hang in there buddy, plenty of time for a change in the weather……

  5. this is true and has been known for sometime, why is this just making news? It will also have a new wiki server as part of Leopard server, it’s all very easy to setup also and the blogs even easier. Hoorah for whole IT deparments who total a number of 1 (like me, lol). Who cares if MS continues to win enterprise wars, let apple go for the consumers.

  6. Microsoft’s Exchange product is very entrenched in IT infrastructure, and many competitors – including IBM – have not yet broken through.

    So if the likes of these industry heavyweights have yet to make a dent, what hope is there for an open source calendar server?

    There’s a long, long way to go before Apple will have a credible (i.e. it works) and viable (i.e. you won’t get fired for installing it) solution to compete with Exchange.

    So show me. I’ll believe it when I see it.
