Microsoft confirmed a major global outage of Outlook, Teams, and other services was caused by a network capacity upgrade issue, not cyberattack or AI. The company is restoring services gradually to ensure stability and will publish a detailed incident report.
This Wire brief sits within Fusion42's coverage of Enterprise Software, and 56 sources have reported it between 12 Nov 2026 and 15 Nov 2026.
◆ ◆ The Wire takeaway
Your enterprise software tools just had their biggest service disruption caused by internal network upgrades, not hacks. Review your cloud dependency backups and test recovery plans this week before this risk hits your business.
