In Mexico and other countries in the region, companies that operate with Microsoft 365 faced interruptions in internal communications and administrative processes, with no immediate alternatives available.
What's next: Microsoft will publish a full post-incident report once its internal review concludes. The company said it will continue to restore service to the remaining customers and regions while monitoring stability.
