Details
Title: Users may be unable to access Microsoft 365 web-based services correctly when using Google Chrome
User impact: Users may be unable to access Microsoft 365 web-based services correctly when using Google Chrome.
More info: Impacted users may experience Microsoft 365 web apps and portals not rendering as expected when accessed via the Google Chrome browsers. This may include, but is not limited to:
- Microsoft 365 admin center failing to load or missing UI elements such as search bars or pages
- An inability to open Excel or PowerPoint files through Microsoft 365 web pages
- Issues accessing apps such as OneDrive and Planner through the browser
Other browsers, including Microsoft Edge, appear to be unaffected.
As a workaround, impacted users can use the Microsoft Edge browser.
Additionally, desktop based clients are unaffected, and users may be able to leverage these services.
Current status: We are updating the authentication components across various service endpoints to remediate the impact. Action has already been taken on a number of endpoints, and internal testing following these changes is showing improvement. Users may need to refresh the browser page to experience relief.
Start time: Wednesday, April 15, 2026, at 7:00 PM UTC
Scope of impact: Some users attempting to access Microsoft 365 web-based services via Google Chrome may be impacted. This information may be updated as our investigation continues.
