Sync Outlook with Kerio Connect Server

Sync Outlook with Kerio Connect Server 

The Kerio Connect Server is a favored messaging solution among mid-sized and small businesses. Notably, it offers beneficial features like contact, calendar, and task sharing, facilitating collaboration within the company.

A decent Exchange alternative

As an Exchange alternative distinct from free mail servers, Kerio offers its own Outlook Connector, allowing Outlook users to access their data on the Kerio Connect Server. However, there have been user reports indicating that it operates sluggishly.

Exploring Mysterious CardDAV and CalDAV URLs

However, if we aim to retrieve CardDAV and CalDAV data from third-party software like Thunderbird on the Kerio Connect Server, we must acquire the URLs for contacts, calendars, and tasks. Although Kerio's KB provides tutorials for this (http://kb.kerio.com/product/kerio-connect/email-clients/mobile-devices/manual-configuration-of-caldav-and-carddav-accounts-1327.html), these URLs often prove ineffective.

In discovering URLs that really work

Here, I found EVO Collaborator for Outlook handy and it works on CardDAV and CalDAV URLs auto discovery. Here is how:

1. Download and install EVO Collaborator for Outlook from its official website
2. Open Outlook and go to Configure profiles
   
   
   
3. Enter your Kerio Connect Server IP like this:
   
   https://<Server_IP>:port
4. Enter username and password. Then click on TEST
5. CardDAV URL and CalDAV URLs will appear, shown as below:
   
   
   

Personal and Public folders 

In ECO's Configure profiles, beside the URLs, there are folder icons that allow you to choose between Personal or Public folders. Opting for the public folder will display public URLs. However, upon examination, we notice that these URLs differ from those instructed in Kerio's KB.

If you utilize Outlook 2007, 2010, 2013, 2016, or 2019, you can proceed with ECO. If you wish to access the Kerio server from Thunderbird, you can simply copy and paste the provided URLs into the SoGO connector and Lightning plug-ins for Thunderbird.
