Sync Outlook with Egroupware server?

Sync Outlook with Egroupware server?

This is an experience sharing from one of my previous jobs. One day, my boss wanted me to do some search on a contact, calendar and task synchronization solution to Egroupware collaboration server to which decided to migrate from a pure paid or free mail server. 

The bottom line is that the solution must be cost-effective and providing perpetual licenses while keeping sync in a simple and straight fashion.

I googled it and found a few candidates: iCAL4OL, EVO Collaborator for Outlook and OutlookDAV. Among them, iCAL4OL is not available. OutlookDAV appears to require way too many steps to configure. EVO Collaborator for Outlook is an add-in within Outlook 2007, 2010, 2013, 2016, or 2019and it takes no more than 6 short steps to configure:

1. Download and install EVO Collaborator for Outlook.
2. Open Configure profile(s)
3. Click on Profile #15 or later as long as it is vacant.
4. In server URL space, enter:
   
   
   
   
   http://egroupware_server_domain/install_path/groupdav.php/
   
   Example:
   https://davtest.egroupware.de/egw/groupdav.php/
5. Enter username & password in corresponding area.
6. Click Test, Apply and Quit.

I think EVO is doing a good job
