A huge Microsoft 365 cloud disruption stopped daily work across 74 countries, including India, the US, and the UK. Important office apps like Microsoft Outlook, Microsoft Teams, and Copilot AI stopped working for over 20 hours, causing major IT trouble around the world.
The problem began late on November 12. Millions of workers suddenly could not check their emails, open calendars, or join office meetings. According to Downdetector, over 1.3 lakh complaint reports came in quickly as corporate offices, banks, and hospitals lost their main way of talking to each other. Many airline operations, including Emirates and Malaysia Airlines, faced email delays with passengers. Staff had to use phone calls to handle customer queries.
Government workflows in several countries also slowed down. Many public offices and courts had to use paper files to keep working. However, India central government offices stayed safe because they use their own separate email system. Microsoft said sorry for the global outage and explained that a server overload caused the cloud downtime, not a hacker attack. While apps are working fine again, this event shows why offices should not depend on just one tech company.
