Info:
Thunderbird does not include its own calendar. In
these instructions, we use the free Lightning add-on on a PC with Windows 7.
-
Install the
Lightning Thunderbird add-on and restart Thunderbird.
-
Press
Alt + D to open the
File menu.
-
In the
New submenu, select
Calendar.
-
Select the
On the Network option and then
Next to continue.
-
Select the
CalDAV format.
-
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.
-
Click
Next.
-
Give the
GMX
Organizer a name and, if applicable, a
color. Appointments from this calendar will later be displayed in the color.
Click
Next.
-
Enter your GMX e-mail address and password. Confirm by
clickingOK.
-
Complete setup by clicking
Finish.
Your
GMX "My
Calendar" default calendar is now synchronized with Mozilla Thunderbird.
