ContactOffice is now a CalDAV server: you can read and write events from CalDAV software such as Mozilla Sunbird, Mozilla Lightning (a plug-in for Thunderbird), Apple iCal and also iCal on iPhone (version 3.0 is needed). Note: Microsoft Outlook 2007 has no CalDAV features.
For other software, see http://caldav.calconnect.org/implementations/clients.html
The settings depend on the software. Please log in your ContactOffice account and read online help for limitations and software settings.
This new feature is automatically available for all ContactOffice accounts.
