My icloud is set to English, but the mailbox invaribly appears in Swedish, Russian (once even Danish).

I do not know whether Apple tries to geolock (I work in Finland and Apple cannot translate Finnish) but this appered less than a year ago. I have been trying Apple support in chat - they no idea either.

To make matters worse, e-mails (which are part of conversations) appear in the scrap folder where I obviously do not really look for them.

So - Apple Mail (whatever the browser and regardless if on Mac or PC) is playing up: what can be done?
