From DAViCal Wiki
So far the available CalDAV clients which have been verified to work with DAViCal in at least some manner are:
- Mozilla Calendar (Mozilla Lightning & Mozilla Sunbird)
- Postbox Postbox and its Postbox Lightning add-on, working very well. (It's paid)
- Kontact / Akonadi (via WebDAV as at Sept 2009)
- iCal version 3.0.1 onward from OS 10.5, and since DAViCal release 0.9.2 onwards
- SOHO Organizer will work with basic functions from DAViCal 0.9.2 onwards, more complete support arrived in 0.9.3
- Outlook Several extensions for Outlook are available:
- Atmail Sync for Outlook A Microsoft Outlook 2007 & 2010 Add-in to open-standard CalDAV (calendaring) and CardDAV (contacts) protocols to sync to the Atmail server (nonfree)
- iCal4OL A perfect 2-Way Synchronization with Google Calendar, DAViCAL and WebCalendar! (nonfree)
- OpenConnector for Outlook 2003+, post 2007-Dec releases. (deprecated)
- OpenChange/SoGo seems to have worked out a built-in solution for their project that may be usable?
- ZideOne A MAPI message store provider which converts Outlook into a real CalDAV/GroupDAV client (nonfree) (deprecated, no longer available)

Clients not confirmed to be working
- OpenConnector for Outlook 2003+, post 2007-Dec releases.
- Just tested on 2010-05-09, to no avail. Don't lose your time, it will never connect to your Davical server, and will only pollute your Outlook client with highly time-consuming extra processes. BTW, this project seems abandoned.
