Microsoft has restored its Microsoft 365 services after a major global outage disrupted operations for more than 24 hours. Popular platforms, including Outlook, Microsoft Teams and Copilot, faced connectivity issues, affecting millions of users across businesses, government offices and other organisations worldwide.
The disruption began on Thursday and spread across at least 74 countries, leaving users unable to access emails, schedule meetings and use several essential workplace applications. Microsoft attributed the problem to an issue linked to an earlier network capacity upgrade that surfaced following a subsequent network change. The company confirmed that the outage was caused by a technical problem and there was no evidence of a cyberattack or malicious activity.
The disruption also affected several important sectors, including healthcare, aviation, financial services and government operations. In India, airlines such as IndiGo and Akasa Air reported problems with their email support services, warning passengers that customer queries might face delays. Several organisations worldwide were forced to rely on alternative communication methods, including phone calls and manual processes, to continue their operations.
Microsoft apologised to customers and business partners for the inconvenience caused by the disruption. The company said it had addressed the underlying technical issue and successfully restored services to the remaining affected customers and regions. It is also monitoring system stability and the processing of delayed emails to ensure that all services return to normal. Microsoft has stated that a detailed post-incident report will be shared following its investigation.
