The Zimbra Connector for Outlook (ZCO) provides real time, two-way synchronization of email messages, folders, tags, address books, tasks, and calendaring between Outlook and your Zimbra account.


ZCO stores a copy of your account data on your computer in a database called a ZDB. This allows you to work with your data even when you are not connected to the Zimbra server.


The attached guide covers installation, configuration, synchronization and other features of ZCO.


Note: With Outlook 2010 and 2013, ZCO functionality is accessed from the Zimbra ribbon on the main Outlook window. For older Outlook versions ZCO functionality is generally accessed from the Outlook menus.
