Microsoft 365 services were fully restored on Saturday after an outage lasting more than 24 hours (incident MO1550821), and the company ruled out a cyberattack, attributing it to a network capacity upgrade issue. The resolution removes a reputational overhang rather than changing financial expectations; a brief service disruption with no disclosed financial damage typically has little lasting price effect.
