Summary:
The message emphasizes the importance of keeping Microsoft Teams desktop clients updated for security and compliance. Teams updates automatically, but admins should ensure this feature is properly configured. Starting November 12th, 2024, outdated clients will receive notifications, and by December 4th, 2024 (on hold), a blocking page will appear for versions older than 90 days. Admins need to prepare by updating Teams and verifying configurations.
Details:
Updated December 3, 2024: We're delaying further rollouts of warning banners and blocking pages in December and intend to resume in mid-January. We'll have a more detailed update later.
In today's security climate, our work across the company and greater industry to keep this critical ecosystem secure is more important than ever. And while we also ship bug fixes and other new features via continuous innovation, in the end security is job one.
Keeping Microsoft Teams up to date is critical to ensure your devices are secure and compliant. By default, and as designed, Teams updates automatically which successfully updates most clients in the world without additional overhead for customers.
Microsoft Teams is governed by the Modern Lifecycle Policy which requires that the Teams desktop client be kept up to date. This is not a new policy, for instance in MC298823 (November 2021), a version that is far out of date will become incompatible with the service until it's updated. As documented, when a client falls out of date, the user will see:
Recurring in-app alerts, if the app is between 30d-90d out of date.
A blocking page in Teams, if the app is greater than 90 days out of date. At this point, the app will show options to update, to contact their IT administrator, or continue to Teams on the web.
As an example, if the Teams app is hypothetically on a version released on January 1 and the next update is fully available on January 15, an in-app alert would be shown on February 14th (30 days after the January 15th update).
For reference, link to the Teams app's version's release dates. Also, The Microsoft Teams desktop client usage report gives you an overview of the Teams desktop clients in use within your organization.
Classic Teams is not in scope for this post; see MC783985 for Classic Teams Timelines regarding end of support and end of availability.
[When this will happen:]
The existing policy enforcement will be visible beginning November 12th, 2024.

summary for non-techies**
Starting November 12th, 2024, Microsoft Teams will notify users to update if the software hasn't been updated for over 30 days, and a blocking page will appear if it's more than 90 days out of date, with similar but slightly different rules for Virtual Desktop Infrastructure starting January 2025.
