Microsoft 365 applications hit by global outage for over 10 hours

What's behind this

Microsoft’s cloud services suffered a global outage that began on November 12 and lasted roughly ten hours, disrupting Outlook, Teams, Microsoft 365, Exchange Online and Copilot for millions of users across 74 countries. The company said a portion of its infrastructure was experiencing elevated load, contributing to connectivity errors, and extended the mail timeout to 48 hours. In India, airlines including Air India, IndiGo and Akasa Air reported email‑based customer support disruptions and issued passenger advisories. Mainland China felt only minimal impact because 21Vianet and domestic applications insulated local firms, highlighting a lesson in data sovereignty.
