Microsoft has begun the progressive restoration of its services following a global outage that impacted users and organizations worldwide, disrupting communication for companies, public administrations, and other bodies. The US-based multinational confirmed that its technical teams are making progress in recovering the affected infrastructure, noting that service availability and email delivery are improving across an increasing number of systems, although a complete recovery has not yet been achieved. The incident specifically affected Microsoft 365, with issues reported in Outlook, Teams, SharePoint Online, the AI assistant Copilot, OneDrive, and OneNote. Microsoft stated that improvements are observed in North America, with favorable evolution in much of Europe and positive recovery signals in the Asia-Pacific region. However, the company warned that some users may still experience intermittent difficulties accessing accounts and delays in message receipt or delivery. While the technical investigation is ongoing, initial explanations point to a problem in the server infrastructure supporting Microsoft 365 services, particularly those related to Exchange Online, the platform that manages email. Reports indicate that several servers unexpectedly became unavailable, forcing the rest of the infrastructure to assume the workload.
The impact was immediate and far-reaching. Downdetector recorded over 130,000 users reporting problems accessing Outlook alone, with similar complaints flooding in from Teams, SharePoint Online, the AI assistant Copilot, OneDrive, and OneNote. The disruption wasn't merely inconvenient—it was a systemic failure that rippled through economies and governments. Companies like OpenAI and Anthropic reported connection issues with Microsoft 365, while Workhorse Group was forced to delay its quarterly earnings call. The Australian Home Affairs Minister Tony Burke confirmed discussions with Microsoft's regional executive, noting that service health remained variable and had not yet returned to baseline.
Microsoft has laid off thousands of employees while investing billions in AI. Now Outlook goes down, and everyone is depending on human engineers to get things running again. It’s interesting how companies keep talking about replacing people until something breaks and they need people to fix it.
For ordinary users, the outage manifested as inaccessible emails, frozen collaboration tools, and disrupted workflows. For organizations, it represented a fundamental breakdown in their digital infrastructure. "Today's outage has affected many of our customers, and we apologize for the inconvenience," Microsoft executive Puneit Chandok stated, acknowledging the disruption. "Our global teams are working with urgency and priority until full resolution."

As the hours passed, Microsoft's technical teams began to piece together what had gone wrong. Initial explanations pointed to a problem in the server infrastructure supporting Microsoft 365 services, particularly those related to Exchange Online, the platform that manages email. Reports indicated that several servers unexpectedly became unavailable, forcing the rest of the infrastructure to assume the workload. "For parts of the affected infrastructure, measures have already been completed and data traffic has been gradually resumed," Microsoft reported in a statement, though the complete recovery remained elusive.
Claude just went down for users worldwide today, November 13. Here's what you need to know. Reports of problems started piling up on X around midday. Users said Claude Code logged them out mid-session, and /login would not run. Others saw "OAuth request failed" when signing in, and the https://t.co/n9TokQatv1 page would not load. Some saw Cloudflare errors, and some said the web app was buggy and the desktop app and Claude Code would not start. Anthropic's status page ties the trouble to a Microsoft outage, now in its second day. The incident is titled as elevated errors affecting the Microsoft 365 connector. It began at 17:52 UTC (12:52 p.m. ET) and was still unresolved. Claude for Outlook remained affected, and Anthropic pointed users to Microsoft's status page for progress. One report said the Claude API, Claude Code and Claude Console were listed as operational. That means the status page shows the problem as limited to Microsoft-dependent features, even though many users could not log in to the app or Claude Code. Another report put the start at 1:33 p.m. PT, affecting https://t.co/xpmg9zlmv4 and the API. The same Microsoft outage also broke the Microsoft 365 connectors in ChatGPT. Key numbers: - Nov 13, 2026: date of the outage - 17:52 UTC: start time logged on Anthropic's status page - 2nd day: how long the Microsoft outage has run - Microsoft 365 connector and Claude for Outlook: services Anthropic listed as affected Anthropic says it will update its status page when service is restored.
The incident bore striking similarities to previous technological meltdowns. "They don't believe they are dealing with a cyberattack," Australian Home Affairs Minister Tony Burke explained. "They believe that they are dealing in some ways with something similar to what we saw with respect to CrowdStrike where there is an update that has gone awry." Microsoft officials echoed this assessment, stating they had "no indication that the outage was caused by malicious activity or a cyberattack."
Microsoft adopted what it described as a "measured approach to identify and repair affected infrastructure." The company reported gradual improvements in North America, with favorable evolution in much of Europe and positive recovery signals in the Asia-Pacific region. Microsoft warned that some users might still experience intermittent difficulties accessing accounts and delays in message receipt or delivery.

While the digital world convulsed, critical infrastructure remained largely unaffected. Deutsche Bahn, Germany's national railway, confirmed that its trains operate independently of Microsoft systems, ensuring stable nationwide service. Similarly, energy company Eon maintained separate systems for information and operational technology, preventing any disruption to power delivery. The German government reported no major administrative disruptions, though officials acknowledged the potential for widespread economic effects.
Microsoft continues to work toward full restoration of services. "Recovery actions are ongoing and have progressed in phases across affected Microsoft 365 infrastructure," the company stated. "However, service health remains variable and capacity has not yet fully returned to baseline." The incident serves as a stark reminder of our collective dependence on cloud services and the cascading failures that can occur when those systems falter. In an increasingly digital world, the line between convenience and critical infrastructure grows thinner with each passing day.
