Question Thunderbird displays the email folder names (like Drafts, Sent, ...) in English now?

[marc@orxo]

Server operating system version

Ubuntu 24.04.2 LTS

Plesk version and microupdate number

Plesk Obsidian Version 18.0.70 Update #1

Good morning everyone,

I run a Plesk server on Ubuntu LTS 24 and recently switched the IP addresses of my dual stack setup. Ever since then, Thunderbird has started displaying the email folder names (like Drafts, Sent, Trash) in English. Before, they were in German. I haven't been able to find any setting in Thunderbird to change this, and as far as I know, the server creates the default folders in English anyway.

Does anyone know how to get Thunderbird to show the folder names in German again? Is this an issue with Thunderbird or with Plesk?
Before, everything worked perfectly fine.

Best regards,
Marc
