Millions of Microsoft Outlook users are experiencing a widespread outage today, July 10, 2025. The issues, which started around 3:50 AM IST, are preventing users from accessing their email accounts across web, mobile, and desktop platforms. This is a developing story, and we’ll continue to provide updates as they become available.
User Reports and Error Messages
Numerous users have taken to social media to report their inability to log in to their Outlook accounts. Common error messages include “Something went wrong” and “invalid license,” indicating a potential authentication issue. The widespread nature of these reports suggests a significant problem with Microsoft’s Outlook infrastructure.
Affected Regions and Services
The outage appears to be impacting users globally, with reports coming in from the UK, Australia, and Canada. DownDetector, a website that tracks online service outages, shows a significant spike in reports, particularly affecting users in major cities like Washington, New York, and Dallas. The issues extend across various Outlook services, including Outlook.com, Outlook Mobile, and the Outlook desktop client, meaning users are unable to access their email regardless of the platform they use.
Possible Causes and Microsoft’s Response
Microsoft has acknowledged the outage and is actively investigating the root cause. Initial reports suggest the issue may stem from underperforming mailbox infrastructure, possibly linked to an authentication component failure. Additionally, a problematic update revision in the storage layer is also being investigated as a contributing factor. Microsoft has stated that they have deployed a fix and expect the issue to gradually resolve as the deployment progresses. However, many users are still experiencing difficulties.
Current Status and What’s Next
As of the latest update, Microsoft’s fix is being deployed, and some users may see a gradual restoration of service. However, many are still experiencing login problems and slow email performance. It is recommended that users continue to monitor Microsoft’s service health dashboard for updates. We will also provide further updates as the situation evolves.
