Microsoft Resolves Back-End Change Causing Teams Free Disruptions

A recent technical glitch affecting the Teams Free platform has left users unable to initiate chats and calls.

The issue is attributed to a back-end modification that circumvented critical onboarding procedures for certain users, resulting in profiles appearing incomplete and inaccessible to others.
The problem began approximately three weeks ago, on April 8, and although specific regional impacts remain unreported, Microsoft characterizes the incident as a “service degradation,” implying notable user consequences without total system downtime.

“We have identified a recently deployed back-end change that caused new Teams Free users to bypass essential onboarding steps, leading to incomplete user profiles and hindering connectivity and chat initiation capabilities,” a Microsoft spokesperson stated.

Affected users found themselves unable to discover, connect with others, or successfully complete chat requests due to this anomaly.

Resolution Efforts

Microsoft representatives have expressed commitment to resolving the issue, with a subsequent update planned to provide further details.

Related Security Concerns

This development follows a separate Teams-related issue where a recent service update was temporarily blocking some customers from launching the desktop client. That problem has since been addressed.

A related security concern involves an AI-powered exploit that successfully chained multiple zero-day vulnerabilities together, evading both browser and operating system sandboxing measures. Industry experts warn of an impending wave of similar attacks leveraging these sophisticated techniques.
