Microsoft Outlook, the widely used email and calendar service, experienced a significant global outage on July 10, 2025, leaving millions of users unable to access their mailboxes across various platforms, including web, mobile, and desktop applications. The disruption began around 10:20 PM UTC on July 9, 2025, and persisted into the following day.
Users attempting to access Outlook encountered a "Something went wrong" error message, preventing them from retrieving emails, managing calendars, or accessing contacts. The outage was not limited to a specific region; reports indicated that users in multiple countries, including the United States, United Kingdom, Australia, and Canada, were affected.
Microsoft acknowledged the issue through its official Microsoft 365 Status handle on X (formerly Twitter), stating that they were investigating the problem and working on deploying a fix. The company identified the root cause as a problematic code change and initiated a rollback to restore services. In a subsequent update, Microsoft reported that the fix was progressing quicker than anticipated and expected the issue to gradually resolve as the deployment progressed.
This outage is notable not only for its widespread impact but also for its duration. Previous outages, such as those in November 2024 and March 2025, were resolved within a few hours. However, the July 2025 incident extended beyond 11 hours, marking it as one of the longest Outlook disruptions in recent years.
The inability to access Outlook services had significant implications for both individual users and businesses. Professionals relying on Outlook for business correspondence, scheduling, and collaboration faced delays and interruptions. Students, personal users, and organizations using Outlook for critical communications were equally affected, highlighting the service’s integral role in daily operations.
As of the latest updates, Microsoft has deployed a fix and is closely monitoring its deployment. Users are advised to stay tuned for further updates from Microsoft regarding the full restoration of services.
This incident underscores the critical dependence on reliable digital communication tools in today’s interconnected world and highlights the importance of robust infrastructure and swift response mechanisms to mitigate the impact of such outages.
