Important services like Teams, Outlook, and Exchange were apparently interrupted by a worldwide Microsoft 365 outage, leaving thousands of customers in a state of confusion as calendars, communications, and businesses came to a complete stop.
Overnight, reports of problems started to surface, and by 8 a.m. ET, complaints had sharply increased.
Over 5,300 complaints had been filed by lunchtime using the outage tracker DownDetector, with the majority of customers mentioning issues with Outlook and Exchange.

Microsoft promptly started reversing the update after attributing the mayhem to a “recent change” in updates sent on X (previously Twitter). The business stated that “manual restarts on a subset of machines in an unhealthy state” were also under progress, but that “we’ve started to deploy a fix.”
Although the firm reported that the update had restored service to 98% of affected settings by midday ET, several customers continued to suffer delays in accessing Teams calendars and Exchange Online. Microsoft acknowledged that progress had been slower than anticipated and said that targeted restarts were still being carried out.
Monday’s outage occurred concurrently with the launch of Recall AI, a new feature intended to record computer activity snapshots for improved searchability, though the business has not disclosed the specifics of the problematic update. The tool’s rollout was postponed because of prior criticism over privacy and security issues.
In recent months, Microsoft has experienced two significant disruptions. A botched update in July led to a global system breakdown that affected healthcare networks, banks, and airlines. Manual device reboots were also necessary for that remedy.
Due to Microsoft’s lack of a definitive schedule for complete restoration, customers were left anxiously refreshing their screens and looking for alternatives to their vital workflows as organizations around the world scrambled to adapt.
