The Language preference setting determines the language for all communications that are sent from your operator to your organization. When you sign up, this setting determines the language used by SharePoint Online, which your users see on your team site. If you change the language preference setting after you sign up, all future communications are sent in the most recent language selected.
Note: The language used by SharePoint Online can’t be changed.
The Language preference setting in the organization’s profile can be different from the Language setting in the user’s profile, as follows:
The administrator selects the preferred language with the Language preference setting in the organization’s profile.
Individual users, including administrators, control the Language setting in their user profiles. The default language is the one selected for the organization, but each user can change it. The language selected in the Language setting determines the language each user sees in Office 365. Go to Settings , click Office 365 settings, and then click Language to change your display language.
