Can Organizations Continue Using Classic Microsoft Teams?
Question details
Organizations need to know if they can continue using the Classic Microsoft Teams client and understand the implications of its end of support and end of availability deadlines.
- Product
- Microsoft Teams
- Device & OS
- not provided
- Scenario
- Planning IT infrastructure updates and managing organizational communication software lifecycles.
- Observed behavior
- The Classic Teams client reached end of support on July 1, 2024, and end of availability beginning July 1, 2025, meaning it no longer receives updates, new features, or server connectivity.
Before rolling out the update, ensure your organization's operating systems and devices meet the minimum hardware and software requirements for the new Microsoft Teams application.
Migrate Users to the New Microsoft Teams Application
To ensure continued support, security patches, and access to new features, organizations must fully transition users to the new Microsoft Teams client.
The Classic Teams client reached its end of support on July 1, 2024. Microsoft completely discontinued the provision of new features and security updates for it. Furthermore, its end of availability began on July 1, 2025, rendering the classic client unusable for organizational communication.
Administrators must take proactive steps to transition all users to the new architecture to prevent service disruptions.
Access the Microsoft Teams admin center and consult Microsoft's official migration documentation to understand the deployment phases and prerequisites.
Test your organization's required policies, third-party integrations, and custom applications to ensure they are fully supported in the new Teams environment.
Push the new Microsoft Teams application to user devices using your organization's endpoint management solution (such as Microsoft Intune), or instruct users to manually toggle the 'Try the new Teams' switch located in the upper-left corner of the classic app.

Frequently Asked Questions
What happens if a user tries to open Classic Teams after July 2025?
Starting July 1, 2025, Classic Teams reached its end of availability. The application will no longer connect to Microsoft services. Instead, users will receive a strict prompt requiring them to download and install the new Teams client to continue using the service.
Will my organization's chat history and files transfer to the new Teams?
Yes. All chat histories, files, channel configurations, and account settings are securely stored in the cloud. Once a user logs into the new Microsoft Teams application with their organizational credentials, all data will sync automatically.
Should we uninstall Classic Teams after migrating?
Yes. While both versions could coexist during the transition period, the classic version is no longer functional after the end of availability. Administrators should deploy an uninstall script or instruct users to remove Classic Teams to free up system resources and avoid confusion.
