        Hi,
that might be the name of the address book you see in the GUI, I think.
I do not speak German, thus I do not know what it tells you.

Right, it cannot. To do that one might open whole file system for the
sandbox, which kind of invalidates the purpose of the (Flatpak)
sandbox, thus Evolution had disabled sendmail, when it is running under
Flatpak. I'll mute that runtime warning to not confuse the users.

Try to execute in the terminal:

   $ export LANG=C.utf8

before executing the flatpak command. You should do that before running
the Flatpak application for the first time, thus also the background
processes will use the C locale (you can use also en_US.utf8 or such).

Here [1] is written where the data is stored. You want the *.source
files. The path may slightly differ in Flatpak, I'm not sure right now.
Run this:

   $ flatpak run --command=sh org.gnome.Evolution

which will start a terminal in the sandbox of the Evolution
application. You can run other commands, explore the directories and do
all other things there.

        Bye,
        Milan
