Microsoft 365 Recovers Globally After Major 24-Hour Outage

Microsoft has confirmed that a major global outage affecting the Microsoft 365 ecosystem is finally resolving after nearly a full day of downtime. The disruption, which kicked off on Thursday at roughly 1 p.m. Eastern Time, blocked numerous users from accessing Outlook emails, certain Microsoft Teams functions, and Copilot tools. Additionally, Apple Mail users experienced problems with their connected Exchange accounts.

While core messaging and calling capabilities largely stayed operational, scheduling meetings and managing calendar entries generated frequent errors for affected individuals and organizations worldwide. According to official statements, the disruption stemmed from a flawed network capacity upgrade rather than a malicious cyberattack or an AI-related glitch. Due to heavy system demand, the tech giant implemented a gradual rollout to guarantee stability during the recovery phase.

Should you buy it? While Microsoft 365 remains an essential suite for productivity and business workflows, widespread server disruptions highlight the ongoing vulnerability of cloud-dependent office software.

We are seeing broad recovery and stability across our services as we work to restore full access to remaining customers and regions.

The company issued an apology to impacted clients and partners, promising a comprehensive post-incident report once an internal review concludes. Meanwhile, the Service Health Status dashboard indicates that minor intermittent issues may still affect a small subset of users until full restoration is achieved.
