Global Microsoft outage knocks out Outlook, Teams and Copilot

Microsoft is struggling to restore Outlook, Teams and other Microsoft 365 services after a global outage that began on Thursday hit users in 74 countries and territories.

Microsoft is struggling to restore its Outlook email service after a global outage disrupted access to its workplace applications in 74 countries and territories, TheCable reports.

The disruption, which began on Thursday, also hit Teams, Copilot and SharePoint, affecting businesses, government institutions and schools worldwide.

In an update on X on Friday, the company said: “We’re observing partial recovery across regions in which we’ve applied these adjustments; however, these actions aren’t resulting in sustained recovery, so we’re reviewing what additional actions we can take to improve overall infrastructure stability.”

Microsoft said some servers had become unexpectedly unavailable, shifting traffic to remaining infrastructure and overwhelming a core process.

Downdetector logged more than 130,000 Outlook complaints at the peak, according to CNN.

In Japan, government workers resorted to physical copies of documents, while the Philippines’ supreme court warned of email delays.

The firm said it was not aware of any malicious activity and would publish a post-incident report detailing the root cause.
