The company was purchased by Yahoo! in September 2007, and subsequently purchased by VMware on Tuesday, January 12, 2010. The software consists of both client and server components. Two versions of Zimbra are available: an open-source version, and a commercially supported version ("Zimbra Network") with closed-source components such as a proprietary MAPI connector to Outlook for calendar synchronization.
