Microsoft is diligently addressing a widespread authentication issue affecting users who access Microsoft 365 web services via Google Chrome version 147. This problem, first identified on April 16, 2026, has resulted in numerous users facing difficulties in loading and interacting with Microsoft 365 applications through the browser.
According to Microsoft’s service health updates, users employing Google Chrome version 147 encounter authentication failures when trying to access Microsoft 365 online services. The core problem seems related to specific authentication settings that are incompatible with the latest Chrome update.
Authentication Challenges with Chrome 147
The issue arises from changes in the authentication processes of Chrome 147, which disrupt the browser’s ability to complete login procedures effectively. This disruption prevents users from signing in or using Microsoft 365 web applications as intended. Microsoft is actively working to identify all problematic configurations and is implementing corrective actions.
Updates from Microsoft’s engineering team have been frequent, with announcements made at various times throughout April 16, suggesting continuous efforts towards resolving the problem. The disruption primarily affects users on the latest Chrome version, sparing those using other browsers or desktop clients.
Impact on Microsoft 365 Users
The compatibility issue specifically impacts web services such as Outlook on the web, Microsoft Teams, SharePoint Online, and OneDrive. Organizations that depend heavily on browser-based Microsoft 365 functions may experience productivity challenges, particularly where Chrome is the predominant browser.
Microsoft advises users facing these issues to consider alternative measures. These include refreshing the browser, switching to other browsers like Microsoft Edge or Firefox, or using desktop Microsoft 365 applications to circumvent browser-related authentication problems.
Recommended Workarounds and Updates
To mitigate the disruption, Microsoft suggests several temporary solutions. Users can refresh their browser pages, which might restore access as server-side configurations are updated. Alternatively, switching to another browser can serve as an interim solution. Utilizing Microsoft 365 desktop applications is also recommended to bypass the current web authentication issues.
IT administrators are encouraged to keep an eye on the Microsoft 365 admin center service health dashboard for real-time updates. Although the exact technical change in Chrome 147 causing the issue remains undisclosed, Microsoft’s prompt updates indicate a dedicated effort to resolve the situation.
As the situation evolves, users and administrators should continuously consult the Microsoft 365 Service Health Dashboard for the latest information. Stay informed by following us on Google News, LinkedIn, and X for ongoing cybersecurity updates.
