Preliminary telemetry suggests roughly ↓ 12% of login attempts are timing out across the Azure authentication layer. IT administrators report spikes in support tickets, while corporate users note delayed access to critical communications.

“We are actively working with our engineering teams to restore full functionality,” a Microsoft spokesperson told Reuters.

The outage coincides with a broader rollout of new security protocols, raising questions about compatibility. Experts at Bloomberg warn that prolonged disruptions could pressure organizations to reevaluate cloud‑email strategies.
