Microsoft Teams Free users face chat, call outage after backend update
AI-generated from multiple sources. Verify before acting on this reporting.
Microsoft is working to resolve a service disruption affecting chat and call functionality for some users of the free version of Microsoft Teams. The outage stems from a recently deployed backend change that inadvertently skipped required onboarding and privacy consent screens for new users.
The issue was identified on Tuesday, April 29, 2026, following reports of users unable to initiate or receive messages and voice calls within the Teams application. Microsoft confirmed the problem is isolated to the free tier of the service and does not impact paid enterprise or business subscriptions.
The disruption occurred after a backend update was rolled out to the platform. The change incorrectly classified new user accounts as already onboarded, bypassing mandatory setup steps. As a result, affected users were unable to complete the necessary privacy consent flows required to activate communication features. Without these steps, the system blocked access to core messaging and calling tools.
Microsoft engineers have identified the root cause and are deploying a fix to restore functionality. The company stated that the update is being pushed to affected systems to ensure new users are properly routed through the onboarding process. Existing users who had previously completed onboarding are not expected to experience interruptions.
The outage has drawn attention from users relying on the free version of Teams for personal and small business communication. While Microsoft has not specified the exact number of users affected, the issue has been reported across multiple regions. The company has acknowledged the impact on user experience and emphasized that the fix is a priority.
Microsoft Teams remains a widely used communication platform, with the free version offering basic chat, video calling, and file sharing capabilities. The service is commonly used by individuals, small businesses, and educational institutions that do not require the advanced features of paid subscriptions.
As of Tuesday morning, Microsoft has not provided an estimated timeline for full resolution. The company continues to monitor the situation and will provide updates as the fix is implemented. Users experiencing issues are advised to check the Microsoft Teams status page for the latest information.
The incident highlights the complexity of managing large-scale software updates and the potential for unintended consequences when backend systems are modified. Microsoft has not commented on whether similar issues have occurred in the past or if additional safeguards are being implemented to prevent recurrence.
Further details on the scope of the outage and the number of affected accounts remain unclear. Microsoft has not released specific data on the geographic distribution of the issue or the duration of the disruption for individual users. The company is expected to provide a post-incident report once the situation is fully resolved.
