On July 10, 2025, thousands of Microsoft Outlook users worldwide faced significant access issues, including problems logging in and loading inboxes, affecting platforms like Outlook.com, mobile apps, and desktop versions.

The outage, which began late on July 9, was reported early on July 10 through Down Detector and caused widespread frustration, with users experiencing error messages such as invalid licenses and 'something went wrong' notifications.

Microsoft's status page acknowledged the ongoing investigation and deployment of a fix, with the company confirming that configuration changes were being applied to affected infrastructure.

Despite progress, full service restoration was delayed, with Microsoft planning to provide another update by 10:30 AM UTC on July 10, as initial fixes encountered complications.

The company indicated it was applying configuration changes and restarting affected components but has not yet identified the root cause of the outage.

This outage is part of a series of recent disruptions, including a shorter outage in June and a more severe eight-day outage in March, highlighting ongoing stability issues.

Microsoft has a history of update-related errors, but there is no evidence linking these past issues to the current outage.

Microsoft's 365 status page confirmed the investigation and deployment of a fix, though the cause remains undisclosed, with the company seeking further comment.

Initial attempts to resolve the outage were hampered by complications, and Microsoft has not yet provided a definitive cause for the disruption.

Some users reported that Outlook services began to recover after hours of outages, but full resolution was still pending as of the latest update.

Many users received warnings about license validity despite current payments, and some accounts showed no payment details, adding to the confusion.

While Exchange Online services were disrupted, other Microsoft 365 services like Teams and OneDrive remained operational during the outage.
