GMX provides:

  • a mail service accessible through IMAP,
  • a file service accessible through WebDAV,
  • a calendar service.

But I've never found if there is any way of accessing that calendar service through a standard protocol (CalDAV or iCal). Is there such an access?

From the help pages:

You can use your GMX Organizer with every application that supports the CalDAV standard or .ics format like Outlook, Thunderbird or Mac OS calendar.

The GMX Organizer can be synchronized with all calendar apps that support the CalDAV standard.


The CalDAV address is https://caldav.gmx.com/.
