A global disruption to Microsoft’s services has affected users and businesses across multiple regions, with Outlook, Teams, OneDrive and the company’s Copilot AI among the products experiencing problems. Reports of Outlook failures reached nearly 140,000 worldwide at about 18:00 GMT on Thursday. Users may be unable to access some files or calendar information, although Microsoft said messaging and online meetings were largely still working. The company described the issue as connectivity problems after several servers unexpectedly became unavailable, putting extra pressure on the systems that remained online. It said recovery efforts were showing positive results, but warned that services could fail again even after being restored. There is no indication that the outage was caused by a cyber-attack.
The disruption highlights how dependent organisations are on Microsoft 365 for everyday communication and collaboration. It has also affected companies that rely on Microsoft infrastructure: OpenAI said it was investigating connection problems that had left some tools behaving unexpectedly, while AI firm Anthropic was also caught up in the impact. Electric truck maker Workhorse Group postponed its quarterly results announcement, citing business disruption from the outage. The incident follows another recent Azure outage that affected Microsoft productivity services and businesses, underscoring the reach of failures in major cloud systems. Microsoft said customers in any region could be affected as it worked to restore service.
