Details:

Summary:
Microsoft Teams desktop client must be updated to comply with the Modern Lifecycle Policy. Unsupported versions will receive notifications or blocking pages starting June 19th, 2024. Admins should ensure regular updates for service reliability and feature compatibility. Non-compliance may lead to service degradation or incompatibility.

Details:
Since Microsoft Teams is governed by the Modern Lifecycle Policy, the Teams desktop client needs to be up to date. Users who are on old versions of classic Teams app will receive in-app notifications to encourage them to update to the latest version of Teams. This is to ensure that users have the latest capabilities, performance enhancements, security features, and service reliability.
This in-app notification will not apply to users on machine wide (non-persistent setup) Virtual Desktop Infrastructure (VDI) deployments. Admins will need to regularly update those users to remain supported on Teams.
Per MC298823 (November '21), a version that is too far out of date will become incompatible with the service until it's updated. Also see MC783985 for Classic Teams Timelines regarding end of support and end of availability.
[When this will happen:]
This will be enforced on June 19th, 2024.
