Microsoft 365 Outages: Outlook and Teams Slowly Recover as Fixes Roll Out

Microsoft Outages: Progress in Restoring Outlook and Teams Services

Microsoft has begun rolling out fixes to address widespread outages that disrupted email and calendar services for thousands of users. As of Monday evening, the company reported “incremental recovery” but did not provide a clear timeline for full restoration.

Extent of the Outage

The issue, primarily affecting Microsoft 365 users, was first reported Monday morning. Over 5,300 users flagged problems on the website Down Detector by noon EST, with the majority (85%) reporting issues with Outlook, followed by Exchange (9%) and SharePoint (6%). By 6 p.m., reports had dropped to fewer than 500.

The outages mainly impacted access to Exchange Online—a cloud-based email service—and Microsoft Teams calendars.

Microsoft’s Response

Microsoft identified a “recent change” as the likely cause of the outage and has since reversed it. The company began deploying fixes as early as 9 a.m. EST, which included manual restarts of affected machines.

While the fixes initially restored service to about 98% of customers by late morning, Microsoft later reported slower-than-expected progress for the remaining users. By 6 p.m., the company noted continued incremental recovery.

Possible Connection to New Features

Microsoft did not specify the exact change that caused the issue. However, the outage coincided with the rollout of a new tool called Recall AI for Windows Insiders. This feature takes regular snapshots of computer activity to create a searchable “photographic memory” on PCs.

The tool, first announced in May, had faced privacy and security criticisms, delaying its full launch. Whether its rollout is linked to the outage remains unclear.

About Microsoft 365

Outlook and Teams are key components of Microsoft 365, a suite of software and cloud-based services widely used by businesses for communication and collaboration. Microsoft Teams enables messaging, scheduling, and video calls, making it an essential tool for modern workplaces.

Microsoft’s Market Performance

Microsoft remains one of the world’s most valuable companies, ranked No. 8 on Forbes’ list. The tech giant, co-founded by Bill Gates and Paul Allen in 1975, reached a $3 trillion valuation in January, becoming the second company to hit this milestone.

Despite the outages, Microsoft shares traded at just over $415 on Monday morning, down 0.3%, even as the Nasdaq gained nearly 0.5%. Gates, a co-founder, ranks as the world’s 15th-richest individual with an estimated net worth of $106.5 billion.

This outage highlights the challenges faced by even the most robust cloud service providers and the ripple effects on businesses worldwide. Users are advised to monitor Microsoft’s updates as recovery efforts continue.
