Hmm... did switch to community in the test-sys. switching Languages in the Webinterface back and forth with my freshly created testmailbox works..
grommunio Web: 3.1.174.b9acf37-lp154.129.2 Gromox:2.0.67.aa9ff04
You could maybe rename the zarafa.dat in the maildir/config/ to see if that helps.
grommunio-admin user query username maildir
This will reset all web-user-settings for the corresponding Mailbox!!!
EDIT: nevermind.. i tried it and the server just recreated everything and even removing the session-files in /var/lib/grommunio-web/{,tmp}/session didn't change anything...
It worked after stopping everything, removing the files and rebooting... (probably the start of the services should have done it..)
so in my case...
systemctl stop nginx.service php-fpm.service gromox-*
rm -Rf /var/lib/grommunio-web/{,tmp}/session/*
mv /var/lib/gromox/user/0/1/config/zarafa.{dat,bak}
reboot
That sounds a bit overboard but well...
