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?"

I wrote a calendaring web app a few years back, and it was certainly a half-done web-based solution some seriously missing features. I wish you had included mine in your survey, because I still don't have any customers for it.

As much as I love the Y2K compliant Office App...

0) Geeks will argue which pen and which paper is the best.
1) The Gentoo crowd will make their own paper from pulp.
2) Where's the ^H on Pen?
3) There are some serious latency issues
4) Sometimes the output is so horrible that others can't read the file.
5) Sometimes the output is so horrible that I can't read my own file.
6) You can backspace on a word processor. You can shake an etch-a-sketch. If you mess up on paper, you need new hardware.

You're not in my company; don't make assumptions about my scheduling.

Yeesh, I take it you don't get too many party invitations in the mail? Your Friday nights are booked up all the way through 2009? How dare someone try to include you in a gathering that might be relevant to your interests!

That's why, at least in Outlook, there are "Propose New Time" and "Decline" buttons. We should get together next Tuesday at 1330 so I can show you these features.

Hire an assistant ... somebody who can come in to your office every minute and put a sticky note on your monitor. That person can also be responsible for syncing your schedule by making lots and lots of photocopies.

In other news, NASA spends 1 million on a pen that writes in space.

Because, you know, pencils are so lower class.

I didn't know CalDav swung that way. You never can tell these days...

Microsoft interoperability is no problem. Judges ordered Microsoft to open their protocols years ago. So of course by now all the protocols are crystal clear.

• 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.

What are you talking about?? Writing clones of commercial software is the prime directive of open source! I'm going to go out on a limb and say that actually there are quite a lot of people who like nothing more than doing exactly that.

Re:Zimbra!

[michrech]

No.

Zimbra does it, does it very well and can be made compatible with full fledged outlook.

You dweebs cant even do a google search before just saying "no", can you?

Unless there are half naked girls in your department, I don't really see a choice here.

Mod parent up! Serious, nothing beats the Pen and Paper, except maybe the pencil and paper. Once they find a simple way to replicate it we will be set.

Maybe they'll invent a machine that's, like, a typewriter attached to a TV screen, connected by wires to other typewriters attached to TV screens, and they all save the words you type onto some sort of permanent magnetic record?

I know, but a man can dream...
