Microsoft outage hits Outlook, Teams and Copilot

Nearly 140,000 people report Outlook problems at the peak: a Microsoft outage also hits Teams and Copilot, with reports coming from more than 70 countries. The first reports reach outage tracker Downdetector on Thursday afternoon. By Friday morning, 13 November, Microsoft says its fixes are not working as expected.

What is behind the outage

Microsoft says its services are having connection problems. According to the BBC, the company blames a heavy load on its infrastructure. Bloomberg reports that a key process on affected servers is overwhelmed, leaving them unable to respond and reducing capacity.

Microsoft says Exchange Online, SharePoint and Defender XDR are also affected. OpenAI and Anthropic report problems linked to their use of Microsoft’s infrastructure. Bloomberg puts the total number of incident reports at nearly 200,000.

Fixes have yet to hold

Microsoft initially said it was seeing signs of improvement. It has since said its fixes are not working as expected. Some regions where it has applied them have partly recovered, but that improvement has not lasted. The company is still working to restore its services.

Microsoft executive Charles Lamanna told the BBC the outage was not a cybersecurity incident. There is no evidence of malicious activity, he said.
