Just testing out Grommunio, running latest 2025.01.1 via the appliance that's offered, to see if it a viable alternative to our small scale on-prem Exchange at our small company.
In the Admin interface, I can't see a way of setting the default language for all users to UK - en_GB - as the only English option appears to be en_US. Strangely, in the webmail interface, en_GB is there.
Any ideas?
