Microsoft fails to solve "as expected" the global outage of Teams, Outlook and Copilot

BarcelonaA global outage of several Microsoft applications has affected more than 430 million people worldwide since this Thursday evening. In 74 countries, Teams, Outlook, and Copilot services have been interrupted for reasons that remain uncertain. The company has ruled out a cyberattack, but for now, it remains unable to restore the service.

“We continue working to recover our servers while we implement more traffic optimization actions to improve service stability and increase capacity,” Microsoft explains in a message on X. In some regions, a “partial recovery” has been achieved, but it has not been possible to make the resumption of service “sustained.”

The service outage affects practically every country in America and Europe, Morocco and Western Sahara, South Africa, much of the Middle East, South Asia, and also Australia. In most cases, users cannot access the affected applications, or are unable to view certain files.

On Thursday evening, the technology company acknowledged failures in accessing Exchange Online mailboxes, its cloud email service in America. But then the problems spread, and shortly after, the company already recognized that there could be connectivity issues “in any region”. According to the company, a part of the infrastructure suffered a “high load” that resulted in connectivity errors.

To manage to recover the service, Microsoft has performed several operations. “We are testing a configuration change to address a problem that is causing servers to fail automatic health checks and become unavailable. In parallel, we have restarted all affected servers and are monitoring health as they return to service”, the company explained. For the moment, however, the problem is not resolved.
