Quality Open Source Calendaring / Scheduling?
Jim R. Wilson writes "In past jobs, I've used Microsoft Outlook/Exchange, Novell Groupwise, and Google Calendar for handling business appointments. I'm sorry to say it, but I have yet to see a rival to Microsoft's scheduling features. On Slashdot I have occasionally read rumblings that there are better open source email and calendaring solutions out there. Can anyone substantiate this claim? What are the OSS alternatives? Can any compete with Microsoft's resource scheduling?"
no
I haven't found much, either. It's either some half-done web-based solution or it's got seriously missing features.
Evolution works great with Exchange; all they need now is to create their own back-end =)
PS. Public folders have gone away in Exchange 2007; big mistake if you ask me. It was a selling point for Exchange.

I think the main problem is we can't really come up with an open source scheduling system that's compelely new and innovative because you need compatibility with people outside your organization.
If we're not coming up with something new and innovative we're stuck making outlook clones. People don't like writing software like that.
It's hard to expect the developers to write a feature they haven't been asked about, and/or don't even know it exists.
In other words, what features do you use in MS products that you haven't found in the free/open source applications?
Jim,
I hate to say this, but unless you give us a few reasons why some of the solutions you have looked at are not sufficient I doubt you will get any meaningful response.It's a pretty common problem when people ask for an open source replacement for a program they have used and were reasonably happy with.
Without some starting point for comparison you will just get dozens of stories about how product X works fine for them.
Insert pithy comment here.
CalDav is the wave of the future, with most calendaring clients supporting it (but not MS), and many servers commercial and otherwise also supporting it (Zimbra). The real coming out party was the commercial release of both OSX Server 10.5 and the client, which have both ends. But guess what, the server is open source: calendar server can be gotten and put on any platform. If you want something today, Zimbra or OSX Server are there for the taking. RedHat has a Messenging product coming out based on Zimbra for this exact purpose.
Apple provides a nice calendar server with Leopard server - but it works with Linux (any anything else running Python) as well...

Scalix http://www.scalix.com/
are the two closest, but honestly, neither is a perfect replacement.
Zimbra pretty much does it all. The web client is top notch, and makes a perfectly fine outlook replacement (Yeah, I know. Just try it, seriously), and its got some serious scaling capacitys (Its used by some of the biggest ISPs around). Yahoo now owns it, so its got some name backing. The catch is the outlook compatible one ISNT so open source, but its pretty cheap.
Citadels pretty nice too, and Ignatius foobar is a cool guy, but its a pretty eccentric product. I think they've kinda been fucked around a bit with outlook compatibility, but I admit I havent checked in a long time.
Excuse the Unicode crap in my posts. That's an apostrophe, and slashdot is busted.
Apple's iCal Server is Open Source PHP (with Twisted Framework) and based on the new CalDAV open standard. Everyone (with the possible exception of Microsoft) is moving to CalDAV as the open standard. Many big companies (Oracle, IBM, Google) are involved with the committee and hopefully the holy grail of inter-operable calendaring systems - including free/busy, invitations etc - is finally on the horizon.
The server just officially went gold with Leopard but has actually been done for a while now. Apple's iCal Server and (closed source) Client are currently the most polished products but now that there is a solid CalDAV server I expect that the various clients with gain alot of polish and other CalDAV servers should start to roll out as well.

PS Microsoft is finally a member but their commitment level is not that of the other partners.

You really want to check out Citadel. It has a very comprehensive feature set -- not just calendars but also email, address books, message boards, instant messaging, access via all standard protocols plus a gorgeous ajax-style web user interface.
The best part about Citadel is that it is very easy to install. There's an automatic installer script right on the web site. No fuss, no muss, just enter the install command and watch it go. No tedious mucking about with integrating all of the pieces yourself, as the entire Citadel system is self-contained.
And the whole thing is GPL, unlike solutions such as Zimbra and Scalix which claim to be open source, but when you actually go there you find out that to get the full feature set you have to buy a commercial version. The Citadel project makes its very best work available to everyone on the same terms.

Up until a few years ago, I would have agreed it was the best solution for most businesses, but times have changed. I don't know what industry you're in, but a lot of larger companies are introducing more Linux and Macs on their networks and the ability to function cross-platform and across a variety of clients is a huge feature for a lot of companies.
Unless you just want to save a couple of bucks, there's nothing magical about an Open Source product that makes it better.According to MS, in order to license the current version of exchange it will cost you $4000 per server + $97 per user + some unnamed fee if you want to interconnect with other companies servers. So, assuming you have 1000 people and two servers, you're looking at over $100K. And for that price you can only use all the functionality if all your clients are on Windows, so your advertising people on Macs and your software development team on Linux both end up running their own little calendaring servers or using a shitty Web interface that has not kept up with the regular client. People with smartphones also end up costing you extra for connectors that allow them to access some of the functionality of your Exchange server, instead of all the functionality of a CalDav server.
To summarize, the failures of Exchange are:
...there's nothing magical about an Open Source product that makes it better.Umm, not magical, but being OSS is a feature, one that Exchange is lacking. It is not the only feature that matters, but it does bring significant benefits, including reduced risk and protection from vendor lock-in.
Rated as funny and, yes, it seems funny today. I'm from time we had secretaries and I miss those times. Scheduling between internal and external (customer) connections is PITA. The secretaries were able to negotiate, no system can do that, it is out of your time. They knew personal things what you never would put to any scheduling system, bring flowers or a bottle of whiskey to next meeting because the big boss has a birthday, whatever. They reminded you of all the papers you will need to take to the meeting, they had your flights ready, they proposed to have another person to go with you or just sending another person because whatever reason, etc. No calendar, scheduling, computer system can never do that and it is out of your time - sometimes a lot! So hire an assistant!
