    I thought a calendar was already available for Thunderbird as a plugin.

    Anyway, I only really use web-based email. I have no need for an email client. Will Sunbird still have stand-alone releases?

      I thought a calendar was already available for Thunderbird as a plugin.

      It is, and yet Thunderbird still isn't a suitable replacement for Outlook in corporate environments. From what I understand, Lightning aims to fix that.

          You would think so. But it doesn't seem to work that way.

          I installed the plugin not long ago, with the expectation that at MINIMUM, you would be able to drag & drop .ics calendar attachments into the calendar. Automatic detection of scheduling requests would be even better.

          It doesn't appear to do even that. As far as I could see, the only way to get scheduling requests into the calendar (regardless of whether you use Sunbird or the Thunderbird plugin) is to save the .ics file to your hard drive and then use the "import" command to import the event.

          Therefore, as far as I can tell, the only advantage to using the Thunderbird plugin at this time, is that it sits in the Thunderbird directory instead of its own directory. And that you open it as a switch to the thunderbird command, instead of as a separate command. Whoop-dee-doo. Not to say that I don't understand that this is a work-in-progress, I am aware of that. I'm sure that .ics detection or drag/drop is high on the to-do list. I still find Sunbird useful, and I'm using it now. I just don't see that there is any level of actual email/calendar integration yet.

          I would love to be wrong about this by the way. Maybe somebody will reply to this and tell me that the plugin has lots of very useful bits - but as long as I have to manage my .ics attachments myself, I can't think of the plugin as getting me much.

      • The problem is that even Lightning will not be a drop-in replacement for Outlook. To use it, departments will have to at least configure their Exchange servers to recognize the IMAP protocol, and even with that change I don't think Outlook and Lightning scheduling will interoperate.

        The only way Lightning can replace Outlook is for everyone in the entire department to completely switch from one to the other. Many IT people are going to see that as too risky, or at least too much work for the reward, and no

      There is actually an intelligent response to everyone making this same tired joke. The Mozilla Foundation retargeted development on seperate applications to simplify things for most users. With that done, one of the next major steps (2.0 timeframe) is to break all the shared functionality out into XulRunner (currently being actively developed).

      Eventually all of the apps (FF, TB, SB) will use XulRunner but still be developed and distributed as seperate applications. This should provide the best of both worlds. It will have the tight integration and lower resource usage of the single suite, but without requiring everyone to deal with the headaches of one big monolithic application.

      To anyone interested I'd really advise heading over to the Mozilla wiki and taking a look at what's going.

        And another project takes a page out of the KDE development book. :) This is exactly the process taken by the Kontact project. A container application that integrates multiple separate applications into a cohesive whole. You can run the individual apps (KMail, KAddressbook, KNotes, Akregator, Todo, Journal, KNode, etc) as separate applications, or you can run Kontact which provides a nice sidebar with links to each component, and gives you a single window for everything.

        Best of both worlds: those that want individual apps can use them as such, and those that like the "everything under the sun integrated together" can use it as such.

    • Wait... now come on, who ELSE are they targetting? Gotta be MS Outlook users.

      I'd say why waste effort then. Move that effort into the Evolution port to win32 (if it exists, I think it does) and concentrate on how to get a pst file into Evolution easily. That's how you'll get Outlook users to move.
      • It isn't Outlook that needs to be targetted, its the Exchange server sitting behind it. Evolution is no real help if you still have to have a Windows box running Exchange sitting in the data center - and thats exactly what you need if you want fully functional and integrated mail/calendaring/directory suitable for enterprise use.

          Evolution is not an answer.

          What needs to be targetted is not Outlook, but Exchange. Having an Outlook copy/rip-off (Evolution) is useless for real enterprise use without the functionality provided by Exchange, which means integrated/shared calendar/email/directory, and to get that you have to be running a Windows box or two (or twenty) loaded with Exchange in your data center.

          Microsoft (IMHO) think Evolution is wonderful. It saves them having to port Outlook to Linux, but still requires the high profit-margin, locke-in, proprietary servers (Evolution) in the background. Why do you think they havn't been screaming "IP Infringement!" about Evolution?

          This will be a different animal. It will run on top of standard protocol (IMAP, HTTP/CalDAV) and will cut Windows and Exchange right out of the picture. It will succeed where others - notably Sun, have failed -- Sun has a 100% solid mail server, a (now) solid calendar server, and a (still somewhat funky) address book server, but fails to capture real enterprise customers because they absolutely refuse to build an integrated desktop client.

          Microsoft will NOT like this. They can see the writing on the wall for the Office suite, and this is liable to hit their only other really profitable hook into the commercial data center - Exchange.

          • I don't know about that, MS-Office (which Outlook is part of) is one of the major cash cow for Microsoft, if not the biggest. I wouldn't be so sure that MS would be willing to sacrifice Outlook as long as they get to keep Exchange. I think the other way around may be more likely.
    • We use Oracle Calendar (formerly Steltor CorporateTime, formerly CS&T, formerly Netscape Calendar) at the University I work for. I'd love to see it integrated with Thunderbird, which is our e-mail client of choice, since it's easy to support on all platforms.
    • Wait... now come on, who ELSE are they targetting? Gotta be MS Outlook users. Nobody uses Oracle Corporate Time.

      Actually, we use Oracle Corporate Time, and we like it a lot. While it's not 100% ideal (and I doubt anything really could be) it does support all the major platforms in use here: Windows, Linux, and Mac. The web client is also very nice, and I actually prefer it over the (Motif) native Linux client.

        Apple's Address Book is a really good example. The Address Book framework back-end is integrated into the system[1]. The Address Book app, the Address Book dashboard widget, and a number of third party address book apps are all wrappers around this. This is hugely useful, since the data is accessible from anywhere, even if you decide never to use Address Book.app.

        • I also think that is great. I think they have to be careful to not cross that line and integrate it too much into the system, but as it stands, it's wonderful to have address book functionality in iChat or Adium (putting your contacts' IM address in address book will have their 'real' name show up in your chat app, if you so choose), amongst other things. Any app can take advantage of the info put in there, and that's a good thing (TM).

    Lightning is the working project name for an extension to tightly integrate calendar functionality (scheduling, tasks, etc.) into Thunderbird.

    Thunderbird is doing what it always does. Keep a lightweight email client around, but for those who want/need calander, they can install an extension to give it to them. A lot of good ideas show up in this.

    Futher, this is not a Mozilla Foundation annoucement.

    A. "Lightning" is simply a project code name to keep from having to type or say "Thunderbird extension for tightly-integrated calendar functionality" all the time. The Mozilla Foundation has not yet announced any plans to add Lightning to its set of supported products under any name; indeed, such an announcement would be premature, as the exact composition of Lightning is still very much under discussion.

    I pitched Outlook for Thunderbird with the Calendar plugin and was happy it migrated all my data from Outlook 2k3 into something a little more standard.

    The only thing I've really missed is a reminder feature for the calendar - I still have to fire up Outlook about once a week to get reminders but I don't use it for email anymore.

    Don't know if Sunbird incorporates a reminder feature and couldn't find anything about it on mozilla.org, but I sure hope so. Developers, if you haven't got a reminder feature yet I could really use one ;-)

      I guess no one on the entire Mozilla Calendar team or the user community, for that matter, has thought of that right? :)

      Not trying to give you a hard time, but what you're asking for would be very, very, difficult. You would essentially have to reverse engineer Microsoft's MAPI over RPC protocol. Many have tried, none have succeeded. Or, if you only support newer versions of Exchange with OWA turned on, use Microsoft's WebDAV based calendar schema built on Exchange WebAccess, like Evolution does.

      Mozilla is doing the best they could I think, they're basing their app on a protocol on the IETF standards track http://ietfreport.isoc.org/idref/draft-dusseault-c aldav/ [isoc.org] If an organization wants to get rid of Exchange entirely, they then can give their Outlook users a MAPI plugin that supports CalDAV. We're an opensource plugin at OpenConnector.org [openconnector.org].

  • I was actually talking about this with my friend last night. If Thunderbird gets a quality calander (task, calander, etc) and contact list it will SMOKE Outlook. First MS Outlook doesn't (as far as I have been able to figure it out) support multiple mailboxes, where they go into different directories and are treated differently (sort rules do not count). Thunderbird handles this well.
    I use (on my home computer) Outlook for work (required) and Thunderbird to handle my four different e-mail accounts. V

    ...and a web content composer, and maybe a crappy IRC client to boot.
  • It sounds like Lightning is a TB extension, while Sunbird [mozilla.org] is a standalone program. What are the pros and cons for each?

    ...but it will be worth it. The goal, of course, is standards-based [groupdav.org] functionality for PIM (Personal Information Management) software. Yes, people really do want a replacement for Outlook, and the open source community would do well to offer complete, end-to-end solutions. Combine the Lightning client with standards-based servers [citadel.org] and you've got a good shot at finally getting people to dump Outlook and Exchange.

    Here's the thing, though: everyone seems to assume that we need an "Outlook Killer" and an "Exchange Killer." This is, in fact, not true. "One size fits all" only works for Microsoft because Microsoft forces that model. In an ideal world, everyone will select the products that fit them best, and those products will all work together. That means some folks might choose Lightning, some might choose Aethera [thekompany.com] instead, and they'd still be able to interact with each other's calendars. On the server side, the dozen or so open source groupware servers such as Kolab [kolab.org], OGo [opengroupware.org], Citadel [citadel.org], and PHPgroupware [phpgroupware.org] would all be able to speak common protocols with Lightning and other clients. Users would choose based on other features; for example, one organization might want strong support for forms-based workflow, another might want rich real-time communications, another might want a large selection of third-party plugins. The idea is to allow people to choose their software based on the feature set, rather than by being locked into one choice because, for example, only Exchange supports all the features of Outlook.

    It's going to take a lot of cooperation but we'll get there.
