Announcing the General Availability of Zimbra Desktop 2.0

We are pleased to announce the general availability of Zimbra Desktop 2.0!  This is a major milestone for the Zimbra team and includes significant feature and performance upgrades.  The difference between Desktop 1.0 and 2.0 is enormous thanks to the millions of downloads, thousands of forum posts, and hundreds of bugs posted by Zimbra customers and community members.

As most readers of this blog know, Zimbra Desktop is a completely unique client.  It’s the only free, cross-platform tool allowing you to meld your worlds on or offline – storing and syncing your email, calendar, contacts, files and documents in the cloud, yet having them locally accessible when on the road.  And now, in Zimbra Desktop 2.0 we have also added management of your Facebook and Twitter accounts.

Of course, Zimbra Desktop is also a valuable complement to the Zimbra Web Client and Zimbra Mobile because it provides organizations the exact same user experience on or offline, thus resulting in no productivity loss as users switch between applications.

Zimbra Desktop 2.0 builds on that success with significant advancements for End Users…

  • In addition to the robust list of features already supported, we’ve added read-receipts, email filtering, tabbed compose, mandatory spell check, three-pane reading view, calendar fish-eye view, and shared access to email folders, calendars, address book and briefcase.
  • Desktop already simplifies our lives by aggregating multiple email accounts (Zimbra, Yahoo! Mail, Gmail, AOL,  Hotmail, etc.). Now it adds the ability to aggregate Social accounts (Facebook, Twitter, Digg, etc.) into the same single user interface.  This is the first and only online/offline Enterprise-grade client that offers aggregation of multiple accounts for email, calendar, contacts and social. It is the true inbox for the way we work today.
  • Desktop’s integrated support for the Zimlet Gallery means users have one-click access to 100+ productivity tools: Meebo, Google Translator, sticky notes, email reminders, email templates and many more.

… and for Administrators:

  • Desktop 2.0 lowers help desk and IT costs by deploying the same application on Linux, Mac and Windows and by having a consistent user experience across web client, mobile client, and desktop client.
  • Desktop 2.0 promotes easier back-up and restore, given all of the data and settings are backed-up in the cloud.
  • Nearly limitless extensions and personalization without IT headaches through the one-click Zimlet Gallery integration.

Given the high download rates of Zimbra Desktop 2.0 beta and release candidates, we assume many Zimbra Desktop 1.0 users have already upgraded.  However, if you haven’t already installed Zimbra Desktop 2.0, existing 1.0 users should note that these significant changes have resulted in changes to the underlying database schema and installation procedures. Translation: Zimbra Desktop 2.0 will be a fresh install on your computer and trigger a re-sync – be sure to read the upgrade notes.

Again, many thanks to the community for its continued support of Desktop. See Zimbra Desktop for more details or to download Zimbra Desktop today!

New Gallery Launches for Sharing Zimbra Extensions

With over 55 million commercial Zimbra mailboxes deployed worldwide, and millions more on open source, there are many users reaping the benefits of our next-generation collaboration experience. Many factors contributed to our rapid adoption — such as integrated conversation views, tagging, sharing, powerful search, and mobility — but one of the most important is the ability to customize and extend Zimbra.

To promote extensibility, the Zimbra platform exposes powerful Theme, Data and Zimlet APIs. With these APIs, you can customize everything from branding and interface styles…to integrating external applications & services…to implementing new features. And with a vibrant Community continually using these technologies to enhance Zimbra, the customization you are looking for might already be available.

To that end, we have been busy at work leveraging new resources from our friends at VMware and are pleased to announce the new Zimbra Gallery as the destination for sharing Zimbra product extensions.

The new Gallery includes improved navigation and search capabilities so it is easier than ever to find extensions for Zimbra. The Gallery supports ratings and reviews so Community members can share their feedback and experiences. It is also much easier to share extensions, update status and highlight your work with improved extension “landing pages.”

Checkout the new Gallery at

Zimbra Gallery

The Gallery includes new Zimlets & Themes as well as some updated favorites such as Appointment Summary, Birthday Reminder, Email Attachment Alert, Email Downloader and Email Quotes.

Please visit the Gallery, download extensions, provide feedback and contribute. We look forward to seeing the library of available extensions in the Zimbra Gallery expand in the weeks and months to come. Enjoy!

Community grows for open-source enterprise apps

Companies and their affiliated communities often sit uneasily together, awkward partners at the software dance. To balance the two, companies often seek to reduce corporate control of community through open-source licensing, but this strategy may be diluted by the common requirement to require community contributors to sign contribution agreements.

Nothing could be worse for the formation of true, code-contributing communities, according to Brian Aker, former director of architecture at MySQL:

[R]equiring contributor agreements destroyed outside MySQL development to the kernel, and left MySQL in a position where no substantial, or many, contributions ever occurred.

And yet most people would point to MySQL’s community (as Microsoft’s Dan Jones does) as a key reason for its success.

Perhaps they’re talking about different kinds of community?

Of course they are, and both kinds are important. MySQL attracted a broad-based user community, one filled with developers who modified and embedded MySQL to meet a vast array of different needs. Did it have a solid base of outside contributors who wrote the core of the MySQL database. No. But at tens of millions of downloads each year and a final sale price of $1 billion to Sun, few in the MySQL community are likely to complain.

The reality is that very few open-source projects succeed in attracting and marshaling significant outside contributions. Linux, Eclipse, and Mozilla all do, and perhaps for reasons I’ve identified before, but they are the exceptions to the rule.

Even so, it’s surprising just how significant the communities are around an increasing number of enterprise open-source projects, which communities include both users and developers, a significant number of whom actively contribute code to these enterprise applications. Who would imagine a community of millions forming around developing and using software designed to help the world’s largest enterprises solve some of their biggest problems? In other words, helping the Man feed…the Man?

Strange, but true.

Jaspersoft today announced some remarkable community numbers. More interesting, however, is that Jaspersoft isn’t alone in this.

Let’s run the community numbers for a few of the more successful open-source application companies, Jaspersoft, Alfresco, SugarCRM, and Zimbra:

Jaspersoft Alfresco SugarCRM Zimbra
Registered community members: 120,000 133,000 130,000 33,000*
Software downloads to date: 10 million 2 million 7 million 5 million*

* Zimbra gave me the number of active forum registrations, which is arguably a better metric than raw forum/documentation registrations, which is what I was able to collect from the other companies.

Remember, we’re talking here about enterprise applications, software at the top of the stack, not operating systems, scripting languages, middleware, or application server software each of which has a built-in audience that naturally dwarfs that of any enterprise application.

These companies are all either cash-flow positive or within striking distance of cash-flow positive. (At least two are profitable.) They’re going concerns selling free, open-source software to enterprise customers and succeeding in an IT recession.

Importantly, these communities are highly additive to the companies associated with them. Zimbra, for example, has more than 50 million paid mailboxes and counting. Alfresco, for its part, has grown every quarter since its formation in early 2005, with its last quarter seeing a 30-percent quarter-over-quarter increase on an already large base.

These are significant outcomes, and they derive from significant communities.

It turns out that while a CRM system may not justify a tattoo, plenty of developers care deeply about such “boring” software and contribute accordingly. Enterprise developers are just as passionate about their software as any other community of developers. They drive adoption and accelerate innovation.

The companies behind the projects, in turn, invest more in open-source software development. It’s a virtuous cycle.

This is why open source makes sense, not just at the infrastructure layer of IT, but all the way up to the applications that make enterprises tick.

Disclosure: In order to be able to present complete data, I turned to companies with which I’m involved as an adviser (SugarCRM, Jaspersoft), former employee (Alfresco), or where I keep close tabs (Zimbra).

Matt Asay is chief operating officer at Canonical, the company behind the Ubuntu Linux operating system. Prior to Canonical, Matt was general manager of the Americas division and vice president of business development at Alfresco, an open-source applications company. Matt brings a decade of in-the-trenches open-source business and legal experience to The Open Road, with an emphasis on emerging open-source business strategies and opportunities. He is a member of the CNET Blog Network and is not an employee of CNET. You can follow Matt on Twitter @mjasay.
