Microsoft 365 Web Services Encounter Google Chrome 147 Compatibility Issue

Microsoft is actively investigating a significant authentication problem that is preventing users from accessing Microsoft 365 web-based services through Google Chrome version 147. The issue, which surfaced on April 16, 2026, has left numerous users unable to properly load or interact with their Microsoft 365 applications within the browser environment.

According to official communications from Microsoft’s service health dashboard, users operating Google Chrome version 147 are encountering consistent failures when attempting to access various Microsoft 365 web services.

Compatibility Conflict Identified

The core of the problem appears to stem from specific authentication configurations within Microsoft 365 that are incompatible with the most recent iteration of Google Chrome. Microsoft has confirmed that this conflict disrupts the browser’s ability to complete authentication flows successfully, thereby preventing users from signing in or loading web-based Microsoft 365 applications as expected.

The company has stated that its engineering team is diligently working to pinpoint all affected authentication setups and to deploy the necessary corrective measures.

Microsoft’s engineering team provided multiple updates throughout April 16, issuing status notices at 1:20 PM, 3:29 PM, 4:18 PM, 5:48 PM, and most recently at 6:10 PM IST. This frequent communication underscores the active engagement of engineers in resolving the incident.

The disruption specifically targets users utilizing Google Chrome version 147, suggesting that this particular browser update introduced a behavioral change that clashes with Microsoft 365’s authentication infrastructure. Services such as Outlook on the web, Microsoft Teams (web client), SharePoint Online, and OneDrive, when accessed through the browser, are among those potentially affected. There have been no reports of impact on users employing other browsers or desktop client applications.

Organizations heavily reliant on browser-based Microsoft 365 workflows may face considerable productivity interruptions, especially in environments where Chrome is the standard enterprise browser.

Workarounds

While Microsoft works towards a definitive resolution, the company has suggested several temporary measures for affected users:

• Refresh Browser Page: In some instances, refreshing the browser page may temporarily restore access as Microsoft implements backend configuration changes.
• Utilize Alternative Browsers: Switch to a different browser, such as Microsoft Edge, Firefox, or Safari, as a temporary solution.
• Use Desktop Applications: Where available, use Microsoft 365 desktop applications to bypass browser-dependent authentication processes.
• Monitor Service Health: IT administrators should continuously monitor the Microsoft 365 admin center service health dashboard for real-time updates and advisories.

Microsoft has not yet disclosed the precise technical alteration in Chrome 147 that triggered this conflict, nor has it provided an estimated time for a definitive resolution. The consistent flow of status updates throughout April 16 indicates active progress by the engineering teams towards a fix.

Users and administrators are encouraged to consult the Microsoft 365 Service Health Dashboard for the latest information as the situation develops.

What You Should Do

• If you are experiencing issues, try refreshing your browser page.
• Switch to an alternative browser like Microsoft Edge, Firefox, or Safari.
• Use the dedicated desktop applications for Microsoft 365 services if available.
• IT administrators should regularly check the Microsoft 365 Service Health Dashboard for the most current updates and guidance.
