Microsoft outage enters second day. First fix failed, servers went down again. ‘no signs of a cyberattack’. Elon Musk Weights in.

Microsoft has spent more than a day trying to get its services back to normal. Its first fix didn’t work. Servers that came back online Thursday crashed again when traffic hit them. Microsoft has since tried rebuilding servers, restricting traffic in some regions and rolling back a network change. It still hasn’t told customers exactly what caused the outage.

Nearly 140,000 people reported Outlook problems at the peak. That’s more than 2,000 times the normal level. Microsoft 365 has roughly 430 million users worldwide.

This isn’t just an email headache. Teams, SharePoint, OneDrive and Copilot were also affected. UK medical practices warned patients they might not receive online inquiries. OpenAI and Anthropic lost access to some Microsoft-connected tools. Workhorse Group postponed its earnings call until Monday, November 16.
