November 25, 2024: Thousands of Microsoft 365 users experienced significant disruptions to their email and calendar services on Monday morning. The outage, which began around 10:30 AM EST, affected a large number of users, with 86% of reported issues related to Outlook.
Microsoft acknowledged the issue and confirmed that a recent change had caused the problem. The company has initiated a fix involving manual restarts of affected machines. While the fix is being deployed, the exact timeline for full service restoration remains uncertain.
The outage coincided with the rollout of a new Recall AI tool for Windows Insiders, which has raised privacy and security concerns in the past. However, it is unclear if the two events are directly related.
Microsoft is actively working to resolve the issue and restore normal service to all affected users.
