Microsoft Teams will stop working on older versions of Windows and macOS
If you’re using Microsoft Teams, it’s time to consider updating your computer to Windows 10 or Windows 11 if you haven’t already.
Microsoft has announced that Teams will soon stop working on older operating systems, and users will need to upgrade to keep accessing the software.
The ultimatum was officially communicated by Microsoft in its Admin Center.
No more access to Teams on outdated systemsStarting October 15, Microsoft Teams will no longer be supported on earlier versions of Windows 10 (21H2 and older), Windows 10 and Windows 11 LTSC, and macOS 11. Users running Teams on these systems will start seeing a banner urging them to update their operating system.
For macOS 12 users, this banner will appear a month later.
Although Teams will keep working for a short period after this warning, the clock is ticking. By January 15, 2025, the Teams client will permanently stop functioning on Windows 10 versions 21H2 and earlier.
