At most, users in 74 countries were affected by the problems, which had serious consequences for everyone from universities, schools and hospitals to publicly traded companies that use tools such as Outlook, Teams and Copilot for work.
Microsoft apologized on Friday:
"We deeply regret the disruption this incident has caused our customers and partners. We are aware of the trust they place in our services and take that responsibility very seriously."
The company says the problems "have no connection to cyberattacks or AI" but were caused by "increased load" on its infrastructure.
