Microsoft is taking a significant step by setting a January 2025 deadline for users of unsupported operating systems, affecting those who still use outdated versions of Windows 10, macOS Big Sur, and earlier systems. Beginning January 15, 2025, these users will no longer be able to access the Microsoft Teams desktop client unless they update to a supported operating system. This move is part of Microsoft’s broader effort to push users toward Windows 11 and newer macOS versions, ensuring that all users benefit from improved security, features, and compatibility.
Notifications Begin October 2024
Starting October 15, 2024, users will begin receiving alerts on their Teams desktop client if they are running an unsupported OS version. These notifications serve as reminders to upgrade their operating systems in order to maintain continued access to Teams. Microsoft is emphasizing that upgrading to Windows 11 and other supported OS versions offers enhanced security and an overall better experience.

Why Microsoft is Making This Move
Microsoft’s decision aims to streamline access to new features, improved performance, and more robust security updates. By ensuring that users transition to supported operating systems, Microsoft hopes to provide a better, more secure experience, particularly as cybersecurity threats continue to evolve. Windows 11, for example, offers improved hardware support and more advanced security features, making it a vital update for users still on older versions of Windows.
This transition may raise concerns for organizations still running on Windows 10 or older macOS versions, but the gradual rollout of notifications and the final deadline of January 2025 gives users enough time to plan their upgrades.
Impact on Organizations and Users
For organizations relying on older OS versions, these changes will necessitate internal planning and IT support to facilitate a smooth transition. As Microsoft Teams has become a cornerstone of remote work and collaboration, staying up-to-date with the latest software will be essential for uninterrupted functionality. This move will particularly affect organizations using LTSC versions, which are designed for long-term support but may not receive regular feature updates.
By giving users and organizations a clear timeline, Microsoft is offering sufficient time to adapt and prepare for the transition to a modern, secure OS environment.
In summary, if you’re still using an unsupported OS version, now is the time to start planning your update to ensure you maintain access to Microsoft Teams. Failing to upgrade by the deadlines means losing access to one of the most important tools for business communication and collaboration.
Conclusion
Microsoft’s deadline for blocking unsupported OS users from Teams represents a major push to modernize its user base. By ensuring that everyone has access to the latest security updates, features, and compatibility improvements, Microsoft is hoping to enhance the overall experience for its users. The phased approach, with notifications beginning in October 2024, provides ample time for users to upgrade and continue using Microsoft Teams without interruption.
Be sure to stay ahead of these deadlines to avoid any disruptions in your workflow!
