How to sync Zimbra contacts and calendar with Outlook?

How do I import Zimbra calendar and contacts to outlook 2007, 2010, 2013, 2016, 2019?

In this year of 2020, more and more jobs require people to work from home due to COVID-19 pandamic. Syncing calendar, contact and task remotely from home in order to cope with colleagues has become an issue for those who have not done this before.

Some of my friends are using Zimbra Network Edition and often compalin that the Zimbra Connector for Outlook ZCO only works with MAPI.

I tried Zimbra Network Edition along with some connector softwares on the market. Amazingly, I found that EVO Collaborator for Outlook works! (not the ZCO which only works with paid version of zimbra)

All I need to do is to correctly enter the server URL below Hostname (CardDAV/CalDAV) or webcal:// URL within ECO as the following:


After fields within the profile have been properly filled out, calendar sync is a breeze.

Not only Zimbra platform supports CardDAV and CalDAV, but also EVO Mail Server has native support on ECO smoothly.
