If you use the 'Lightning' add-on for Thunderbird, you can configure automatic synchronization. Due to the technical limitations of Thunderbird, you have to synchronize each of your calendars (default calendar and other calendars) individually.

Info:

Thunderbird does not include its own calendar. In these instructions, we use the free Lightning add-on on a PC with Windows 7.

1. Install the Lightning Thunderbird add-on and restart Thunderbird.
2. Press Alt + D to open the File menu.
3. In the New submenu, select Calendar.
4. Select the On the Network option and then Next to continue.
5. Select the CalDAV format.
6. In the Location field, enter the path https://calendar.gmx.com/begenda/dav/your GMX e-mail address/calendar.

Example: For the e-mail address john.doe@gmx.com, you enter https://calendar.gmx.com/begenda/dav/john.doe@gmx.com/calendar/ as the location.

7. Click Next.
8. Give the GMX Organizer a name and, if applicable, a color. Appointments from this calendar will later be displayed in the color. Click Next.
9. Enter your GMX e-mail address and password. Confirm by clickingOK.
10. Complete setup by clicking Finish.
