Zimbra Collaboration Suite is the world's #1 Open Source Microsoft Exchange alternative. Much more than just email, Zimbra is an enterprise-class email, calendar, contact, and collaboration solution. It was built from the ground up to be delivered via the cloud. Zimbra offers a browser-based interface that rivals what you would expect from a native collaboration application, such as Microsoft Outlook. If you prefer to continue to use Microsoft Outlook, Zimbra's Connector for Outlook provides native Outlook integration.
