Microsoft has resumed full operations for Outlook and other Microsoft 365 services after a global outage that lasted more than 24 hours. The company attributed the disruption to an earlier network capacity upgrade. The outage affected millions of users worldwide including businesses, government agencies, and airlines.

The outage began on Thursday and continued into Friday, causing significant disruption. Microsoft confirmed that it had restored all services by Friday evening. The company apologized for the inconvenience and promised a detailed investigation into the cause of the outage. It ruled out any malicious activity as a potential cause.

This is the second major outage affecting Microsoft 365 services in recent months. In June 2024, a similar incident disrupted Outlook and Teams for nearly 18 hours. At that time, Microsoft also blamed a network upgrade and promised to improve its infrastructure. The current outage has raised concerns about the reliability of cloud-based services.

Microsoft has not yet released the full details of the investigation. However, it has committed to providing more information in the coming days. The incident highlights the growing reliance on cloud services and the potential impact of outages on global operations.
