Millions of users relying on Microsoft Outlook and Hotmail for their daily communications faced significant disruption on Thursday, July 10, 2025. A widespread outage left people unable to access their email accounts, causing frustration globally. This major incident primarily impacted login capabilities and server connections across both platforms. Investigations and attempts to resolve the issue were underway throughout the day, but users were left grappling with the uncertainty of when full service would be restored.
What Happened: Details of the July 10 Outage
The widespread issues affecting Microsoft’s email services on July 10 didn’t begin without warning. According to reports, intermittent problems with Microsoft Outlook first surfaced the evening before, around 7:35 p.m. ET on Wednesday, July 9. Initial reports were relatively low, around two dozen. Hotmail followed shortly after, seeing its first signs of intermittent trouble around 7:40 p.m. ET with just over 30 reports.
Global Impact and Affected Regions
By Thursday morning, the situation escalated dramatically. The outage ballooned into a global issue, impacting users across numerous countries and major cities. Reports poured in from places like the United Kingdom, United States, India, Canada, Germany, France, Switzerland, Russia, Greece, Finland, Sweden, Australia, Brazil, Denmark, Hungary, Ireland, Italy, Peru, Spain, and The Netherlands. Within affected countries like the UK, cities such as London, Manchester, Birmingham, Newcastle, and Glasgow saw significant numbers of reports.
Specific Problems Users Faced
The nature of the problems was varied but centered heavily on access. The most frequent complaints involved users being unable to log in to their accounts. Many encountered frustrating generic messages like “something went wrong” or received notifications that their credentials were incorrect, even when entering the right password. Some users were presented with unsettling errors suggesting their software license was invalid or that no payment details were available for their accounts, despite having valid subscriptions.
Other reported issues included persistent server connection failures. Users saw specific technical errors like 500 and 401 error codes across different devices and browsers. A 500 error typically signals an unexpected server problem, while a 401 error points to failed authentication. Even users who managed to log in reported severely sluggish performance, describing the service as “painfully slow” and sometimes being unable to send or receive emails.
The Scale of the Disruption
Outage tracking websites, like DownDetector.com, provided a real-time snapshot of the unfolding crisis based on user reports. By Thursday morning, the number of reported issues for both Outlook and Hotmail had soared past 1,100 reports for each service individually. The peak number of combined reports cited in the early hours of the outage reached over 2,100 reports as of 9:12 a.m. ET, and continued to climb shortly after.
Data cited from DownDetector during the outage revealed the breakdown of reported problems. While some sources reported 61% citing login issues and 34% server connection issues for Outlook/Hotmail combined, others provided slightly different figures: 53% for general Outlook access, 37% for specific login problems, and 11% for server connection issues. Regardless of the exact percentages, it was clear that login and connection failures represented the overwhelming majority of user difficulties. At the time of some reports, the outage in the UK alone had been ongoing for at least seven hours, and overall, the disruption lasted for more than 12 hours for many users.
Microsoft’s Response and Efforts
Facing a major disruption impacting millions, Microsoft acknowledged the widespread issues affecting its email platforms. Initial statements indicated that the company was actively investigating the problem. They quickly suspected an issue within an authentication component of their systems might be the root cause preventing users from logging in or accessing their mailboxes.
The Attempted Fix and Subsequent Setback
Microsoft engineers began working on deploying a fix they believed would resolve the authentication issues. Early communications from the company suggested some optimism, indicating that the deployment of this fix was progressing quicker than anticipated. They initially hoped that this would lead to a gradual mitigation of the impact on affected users.
However, this optimism was short-lived. In a subsequent update, Microsoft revealed a significant setback: they had identified an issue with the fix they were deploying. This complication meant the initial resolution process was delayed. Engineers then shifted to applying configuration changes, restarting affected system components, and performing additional validations to ensure their authentication infrastructure was properly configured.
Lack of ETA and Communication Challenges
Despite identifying the suspected cause and actively working on deploying a revised solution, Microsoft did not provide an estimated time of arrival (ETA) for the full restoration of services. This lack of a clear timeline left affected users globally uncertain about when they would regain access to their critical email accounts. While official updates were being shared through specific channels, the perceived absence of timely and transparent communication on mainstream platforms like official social media accounts drew significant criticism from frustrated users during the peak of the outage.
Other key Microsoft services, such as Microsoft Teams, Skype, and Microsoft 365 core functions (like OneDrive), were reportedly functioning normally during this period, suggesting the issue was primarily isolated to the Outlook and Hotmail email infrastructure.
Why This Matters: Impact and User Frustration
An email outage of this magnitude, affecting services used by over 400 million people worldwide, has significant real-world consequences. For many, particularly professionals and businesses, Outlook and Hotmail are essential tools for daily operations. The inability to log in, send, or receive emails brought work to a standstill for countless individuals, directly impacting productivity and potentially causing financial losses.
Anxiety Over Account Access and Data
Beyond immediate disruption, the prolonged outage sparked considerable anxiety among users. Many have relied on these email accounts for years, even decades, using them for critical personal records, professional contacts, and essential communications. Fears arose that long-held accounts or the extensive history of emails they contained could be at risk due to the technical issues.
Social Media Reactions and Venting
Frustrated users quickly turned to social media platforms like X (formerly Twitter), Reddit, and Facebook to share their experiences and vent their frustrations. The sheer volume of complaints highlighted the global scale of the problem. Users reported being stuck in endless password loops, constantly receiving error messages, and expressing anger over the perceived lack of clear, timely updates from Microsoft during the crisis. The inability to simply access email sparked a firestorm of online complaints.
What Users Should Do
During a widespread outage like the one on July 10, it’s crucial for users to rely on verified information and take measured steps rather than potentially exacerbating the problem.
Checking Official Status Updates
The most reliable source of information during a Microsoft service disruption is Microsoft’s official service health status pages. These pages are designed to provide real-time updates directly from the company. Users should monitor the Microsoft 365 Service Health status or the specific Outlook service status page for the latest information on the incident, acknowledgment from Microsoft, details on the investigation, and any estimated timelines for resolution, if provided.
Avoiding Risky Actions
It’s often a natural reaction to an inability to log in to try resetting your password repeatedly. However, during a confirmed outage related to authentication or server issues, repeatedly attempting password resets is generally not recommended. This action is unlikely to fix the underlying problem and could potentially lead to account lockout issues or other complications once the service is restored.
Considering Alternative Communication
While Outlook and Hotmail were affected, reports during the July 10 outage indicated that other Microsoft services like Teams and Skype were functioning normally. For urgent communications that don’t require email, exploring alternative platforms or contacting colleagues/contacts via phone or messaging apps became necessary for many affected users.
Frequently Asked Questions
What specific problems caused the July 10 Outlook/Hotmail outage?
During the July 10 outage, the primary issues reported by users were related to login failures and server connection problems. Users were locked out of their accounts, received messages saying their credentials were wrong, encountered errors about invalid licenses, and saw technical codes like 500 and 401 errors. Some users also reported extremely slow performance even if they could briefly access their mailbox. Microsoft’s investigation initially pointed towards an issue with an internal authentication component as the likely root cause.
Where did users report issues during the July 10 Microsoft email outage?
Users reported experiencing difficulties with Microsoft Outlook and Hotmail globally. Affected regions included the United Kingdom, United States, India, Canada, Germany, and many others across Europe, Asia, and the Americas.

Frustrated users also took to social media platforms like X (formerly Twitter), Reddit, and Facebook to share their experiences and seek information.
What did Microsoft advise users to do during the July 10 Outlook/Hotmail outage?
During the July 10 service disruption, Microsoft advised users that they were investigating and working on a fix. While no specific user actions were mandated to resolve the outage, the implicit advice was to monitor official Microsoft service health status pages for updates rather than attempting troubleshooting steps on their end that would not fix the system-wide issue. Experts also advised users to avoid repeatedly attempting password resets, as this action would not help and could potentially cause further complications with their accounts once the service was restored.
Conclusion
The Microsoft Outlook and Hotmail outage on July 10, 2025, represented a significant service disruption for millions worldwide. Centered on critical login and server connection issues, the incident highlighted the dependency individuals and businesses have on reliable email access. Despite Microsoft’s efforts to diagnose and resolve the problem, including attempting and subsequently identifying an issue with their initial fix, a firm timeline for full service restoration remained uncertain throughout the peak of the event. As with any widespread service disruption, the most effective approach for affected users was to stay informed via official Microsoft channels and refrain from actions like frequent password resets that could complicate account access once stability returned.
