Microsoft Teams: Regional Settings Separation

Updated September 3, 2025: We have updated the timeline. Thank you for your patience. Introduction We're introducing the Regional Settings Separation feature in Microsoft Teams to improve the globalization experience and provide users with greater control over their regional preferences. With this update, users can independently configure UI language, date format, and time format within Teams, either by syncing with their operating system or manually selecting their preferences. This change helps eliminate synchronization issues and ensures a more personalized and consistent experience across devices. This update is associated with Microsoft 365 Roadmap ID 498895. When this will happen Targeted Release: Begins early August 2025; expected to complete by mid-August 2025. General Availability (Worldwide): Begins mid-August 2025; expected to complete by late August 2025. General Availability (GCC, GCC High, DoD): Begins mid-August 2025; expected to complete by late September 2025. How this affects your organization Once this feature is rolled out, users on Teams Desktop Client for Windows and Mac will be able to view and modify their date and time format settings directly in Teams by navigating to: Settings > General > Language and regional formats By default, Teams will continue to follow the operating system settings unless users choose to override them manually. This update does not change existing behavior unless users take action. What you can do to prepare No admin action is required. The feature will be available automatically once users update to the supported Teams client build. There are no admin controls or configuration options for this feature. You may consider notifying your users about this update to help them take advantage of the new customization options. Compliance considerations No compliance considerations identified, review as appropriate for your organization.
