The Microsoft 365 outage entered its third day on Friday, disrupting Outlook, Teams, and Copilot across 74 countries after nearly 48 hours of service disruption. The incident began Thursday, November 12 at approximately 17:54 UTC when a core process in Exchange Online failed, triggering cascading failures across Microsoft’s infrastructure, according to Forbes. Microsoft confirmed the issue was not a cyberattack but rather elevated load caused when some servers failed and redirected traffic to remaining servers, overloading them.
Within an hour, DownDetector reports of Outlook problems climbed to roughly 130,000, with users reporting issues across Teams, Copilot, SharePoint, Intune, and Microsoft Defender. At its peak, users in at least 74 countries were affected, Wire reported. Exchange Online’s central role in the Microsoft 365 ecosystem meant the impact cascaded rapidly — when email authentication broke, Teams meetings couldn’t schedule, Copilot went silent, and security tooling stopped functioning.
Layoffs and Infrastructure Investment
Microsoft has cut over 21,000 jobs this year while projecting roughly $190 billion in capital expenditures for 2026, much of it driven by AI and cloud infrastructure demands, the company disclosed in its Q3 earnings. The contrast — cutting tens of thousands of workers while spending nearly $200 billion on AI hardware — has attracted sharp criticism as the outage drags on. The company has shrunk its workforce by more than 23,000 positions across three rounds since May 2025, according to Quartz’s layoff tracker. The cuts included 4,800 roles eliminated in July, plus buyout offers extended to 9,000 US employees in April and 60,000 employees across four countries in October.
Institutional Knowledge Concerns
The outage has surfaced deeper concerns about institutional knowledge loss. Fast Company reported that workforce reductions and restructurings can push out experienced employees who understand how a company’s systems work, including any longtime bugs or quirks, and who know how to respond when something breaks. Even if layoffs don’t directly cause technical problems, the loss of institutional knowledge can make those problems harder to solve. There is no evidence that the layoffs directly caused Thursday’s outage, but the incident has highlighted the risk when companies replace experienced engineers with AI tools.
Recovery Progress
By Friday morning, Microsoft said it was seeing encouraging recovery progress but acknowledged that some users still experienced intermittent access and delayed email delivery. Microsoft tracked the incident under IDs MO1550821 and EX1550543. The disruption comes amid ongoing scrutiny of AI-driven workforce changes across the technology sector, with the outage duration nearing the 48-hour mark.
Weekly updates on tools, models, and the companies building them. OpenAI has raised $15 billion at a $1.25 trillion valuation, roughly half the $30 billion it originally sought, as it builds a war chest ahead of rival Anthropic’s IPO. The raise comes as OpenAI burns through cash with Q3 operating losses of $10.9 billion despite revenue nearing $10 billion. Anthropic’s $64 billion IPO roadshow is six times oversubscribed after three days, with CEO Dario Amodei pitching investors on AI safety, a strict hiring culture, and a $895 billion compute spending plan. Pricing is expected November 18 with trading under ticker ANT on November 19. OpenAI launched ChatGPT Wallet, a payment system that lets its Dots AI agents make purchases without accessing users’ actual card details. Built with American Express, Mastercard, and Visa, it requires biometric approval for every transaction and starts with US ChatGPT Pro subscribers. Qualcomm has started cutting jobs in India as part of a global restructuring, with more than 1,000 roles at risk across Bengaluru, Hyderabad, and other cities. The chipmaker’s revenue fell 3% to $43.1 billion in fiscal 2026, with smartphone chip sales down 25%. Cybersecurity unicorn Axonius is cutting 66 jobs, including 22% of its Israeli developers, as it reshapes engineering around what its CEO calls a new AI-driven way of working. Xbox Game Studios head Craig Duncan is stepping down just 20 months into the role, alongside chief of staff Louise O’Connor, as Microsoft’s gaming division prepares another round of mass layoffs. Compulsion Games, the studio behind 2025 critical hit South of Midnight, is also being shut down.
