Installing the Zimbra Connector for Outlook (ZCO)

Where to download the Zimbra Connector for Outlook, which lets classic Outlook work with your Zimbra mailbox.

Download the connector from Zimbra directly, at zimbra.com/product/download. The installer includes its own instructions.

Match the connector to your mailbox. Its version should be the same as the Zimbra server or higher, never lower. If you already have it installed and are seeing sync errors, see ZCO sync failure notices.

If you are moving to Zimbra rather than just connecting to it, read migrating mail into Zimbra first, because how you bring existing mail across matters more than the client you read it in.
