Microsoft has confirmed that a fix has been deployed to restore email and calendar services to thousands of users worldwide, following a significant outage reported on Monday morning.
However, the exact timeline for full restoration remains unclear.
As of 10:30 a.m. EST, over 2,100 users had reported issues with Microsoft 365 on the website Down Detector. The majority of complaints—86%—were related to problems with Outlook, while 9% involved Exchange and 6% with SharePoint.
The outage primarily affected Exchange Online, Microsoft’s cloud-based email server, and Microsoft Teams calendars.
In a post to its Microsoft 365 account on X (formerly Twitter), the company stated that it had begun deploying a fix by 9 a.m., which involved “manual restarts on a subset of machines that are in an unhealthy state.” While the fix was in progress, Microsoft did not provide an estimated time for when full service would be restored.
The company suggested that a “recent change” was likely responsible for the disruption and assured users that this change had been reverted. However, Microsoft did not specify the exact nature of the change.
The outage occurred on the same day that Microsoft rolled out a new Recall AI tool for Windows Insiders. This tool, designed to take regular snapshots of computer activity for later search, had raised privacy and security concerns when it was initially introduced in May, causing the full launch to be delayed.
Microsoft Teams, part of the Microsoft 365 suite, is used by approximately 320 million people each month, making it a critical tool for collaboration and communication in many businesses worldwide.
While Microsoft continues to work on restoring services, users are advised to stay updated on progress through official channels.
