You can view your display language, time zone, country/region, and related settings at any time from your personal profile page, which you can access from your desktop or laptop devices. And, if your organization policies allow it, you can edit these settings. Your settings apply only to your view of your organization’s SharePoint sites and do not affect how other people view these sites.
Note: If you’re working in an environment of local SharePoint sites that your organization manages—and not an Office 365 environment—your site collection administrator must make the language available for you to use before you can use the language-dependent guidance in this article.
Note: If you set your language in SharePoint Online and then change it in Office 365, the Office 365 setting will override the SharePoint setting.
Note: The features described in this article depend on whether your organization has set up or customized personal sites and user profiles. For more information, see your administrator.
To edit your SharePoint site language and region settings:
Click your name at the top of any of a SharePoint or Office 365 site in your organization, and then click About me.
Click edit your profile on the Edit Details page.
Click the ellipsis (…), and then click Language and Region.
Update your settings. You can use the table that follows this procedure for guidance.
Click save all and close.
