Microsoft will prompt users to update their operating systems to continue using the new Teams client, as support for outdated systems will end. Starting October 15, 2024, users on Windows 10 version 21H2 and earlier, Windows 10 and 11 LTSC, and macOS 11 will receive notifications to upgrade. Teams will cease functioning on these unsupported operating systems by specific dates: January 15, 2025, for Windows 10 version 21H2 and earlier; August 15, 2025, for Windows 10 and 11 LTSC; November 15, 2024, for macOS 11; and March 15, 2025, for macOS 12. Users on unsupported systems will see a blocking page when attempting to launch Teams, requiring them to update. Microsoft recommends IT administrators to regularly update operating systems to avoid service disruptions.
