Résumé détaillé

Microsoft has resolved its global outage after more than 36 hours, restoring Outlook, Teams, Copilot and other services. To remind you, the disruption affected businesses, airlines and government organisations across more than 70 countries.

Microsoft has finally resolved its global outage after more than 36 hours of disruption, restoring access to Outlook, Teams, Copilot and other Microsoft 365 services.
