Latest Release Features Innovative Enterprise-Class Services,
Including BlackBerry and Outlook 2007 Support, Plus New Web 2.0 IM and
Task Applications — Extending Yahoo!’s Leadership in E-Mail Services

SUNNYVALE, Calif., Feb 05, 2008 (RUSHPRNEWS) — Zimbra, a Yahoo! (Nasdaq:YHOO) company, and the leader in open source, next-generation e-mail, today announced the availability of Zimbra Collaboration Suite (ZCS) 5.0. ZCS 5.0 includes hundreds of enhancements that expand Zimbra’s access across desktops and devices while setting the standard for Web-based productivity in a business environment, and showcases Yahoo!’s dedication to providing world-class e-mail and collaboration services. 
Yahoo!’s global reach and Zimbra’s expansive partner network are fueling continued growth, reaching key audiences including universities, ISPs and small businesses — further extending Yahoo!’s overall leadership in e-mail, a key daily starting point for Web users today.

“We are proud of our achievements in ZCS 5.0 and appreciate the passionate feedback from the 13,500 open source community members and customers that made our most significant release to date a huge success,” said Satish Dharmaraj, Yahoo! vice president and Zimbra co-founder. “Together, we have built one of the world’s premier e-mail and collaboration products, and with Yahoo!’s support, are continuing to innovate at a more rapid pace.”

Enhancements in ZCS 5.0 extend Zimbra’s best-of-breed anywhere access on the desktop, including support for Microsoft Outlook 2007, and on virtually any device, with support for BlackBerry Enterprise Server, J2ME-enabled handsets such as the Motorola RAZR, and a new version of ZCS for mobile web browsers. New features in the award-winning Zimbra AJAX Web client include instant messaging, briefcase, and task applications as well as Zimbra Desktop, the world’s first offline-capable Web 2.0 collaboration experience.

“Zimbra has the broadest device and desktop support options of any e-mail and collaboration solution, plus advanced Web 2.0 features in the browser,” said Dervilla Mullan, head of Eircom Online, Eircom. “For Eircom, its superior features match our consumer and small business customers’ needs and support our monetization model better than any alternative we evaluated.”
“Support for BlackBerry Enterprise Server is a huge advantage for Zimbra. From a business standpoint, it’s the last box to check in a product evaluation, and Zimbra is the only open platform that offers it,” said David Smith, group technical director, Gyro International Ltd.

New features in ZCS 5.0 include:
— Native e-mail, contacts, calendar, and task synchronization from Zimbra to Outlook 2007
— Access Zimbra on all BlackBerry handsets, J2ME enabled devices, or any mobile web browser, including the Apple iPhone
— Zimbra Tasks monitor start and due dates, priority, progress, and percent complete of tasks
— Built directly into ZCS, Web-based Instant Messaging supports multiple conversations and group chats
— Conveniently store any file from an e-mail in Zimbra Briefcase instead of as an e-mail attachment; easily share Briefcase folders with others
— Work online or offline with Zimbra Desktop, the AJAX experience for Zimbra users and users of existing POP and IMAP e-mail servers
— Share inboxes and e-mail folders with others, including the ability to provide read-only-access or allow others to completely manage
— Fifteen fully certified languages ship within ZCS for end-users to choose
New Yahoo! and Zimbra Integrated Services
New Zimlets in ZCS 5.0 leverage Yahoo! properties, including Flickr, Yahoo! Local, Yahoo! Finance, and Yahoo! Search. Later this year, Zimbra’s innovative technologies will be incorporated into properties including Yahoo! Mail and Calendar.
“As CEO Jerry Yang previewed at CES, the future of Yahoo! Mail is a smarter more open e-mail experience for all of our users,” said Brad Garlinghouse, senior vice president, communications and communities, Yahoo!. “We will leverage Zimlet-like technology that currently exists in Zimbra’s offering to help advance our goal of creating a smarter inbox that will delight hundreds of millions of Yahoo! Mail users worldwide.”
Yahoo! has been a global leader in e-mail for more than ten years, with Yahoo! Mail exceeding one billion visits each month. Yahoo! Mail remains at the forefront of innovation in Web e-mail, and by leveraging Zimbra’s innovative, open technologies, will continue to give users a more dynamic Web 2.0 experience. This is a vital part of Yahoo!’s strategy to become the starting point for the most consumers on the Web.
