Ah, thanks for the hint!
I created an override for the systemd unit file and set the environment variable:
systemctl cat kopano-server
# /lib/systemd/system/kopano-server.service
[Unit]
Description=Kopano Core Storage Server
Documentation=man:kopano-server(8) man:kopano-server.cfg(5) man:kopano-admin(8)
After=network.target mysql.service mariadb.service
[Service]
Type=simple
ExecStart=/usr/sbin/kopano-server -F
ExecReload=/bin/kill -HUP $MAINPID
TimeoutStopSec=60
[Install]
WantedBy=multi-user.target
# /etc/systemd/system/kopano-server.service.d/override.conf
[Service]
Environment="LANGUAGE=de_AT.utf8"
Halfway there. Now the folder is displayed like this:

Anything else I’m missing?
Thanks!
