Supported Desktop Applications

Your calendars can be synchronized with all applications that support the CalDAV standard. The .ics format is supported for exports and imports.

The mail.com Organizer can be synchronized with any calendar applications that support the CalDAV standard. mail.com offers this option as an additional service and has no influence on whether and at what price applications with CalDAV are available for your device or system.

You can transfer appointments from a calendar application to the mail.com Organizer if the calendar application supports exports in the "iCalendar" (.ics) format.
