A significant Microsoft outage is disrupting global access to essential services such as Outlook, Teams, and Exchange Online, leaving businesses, government agencies and individual users grappling with the consequences. Beginning early Monday morning, the outage has escalated, with over 5,000 users reporting issues by noon on Downdetector. As of this writing, while Microsoft reports progress on remediation, widespread issues persist.
About twelve hours ago, the company acknowledged the issue, stating that “we’re investigating an issue impacting users attempting to access Exchange Online or functionality within Microsoft Teams calendar. For more information, please refer to MO941162 in the admin center.”
Teams, Outlook, Exchange, SharePoint—All Impacted
The outage has hit Microsoft Teams’ calendar functionality, Outlook email services, Exchange Online, and SharePoint—tools fundamental to the workflows of millions, as reported by BleepingComputer. Major urban centers like New York, Chicago, Los Angeles, and Tampa are experiencing notable service disruptions. While some users report partial functionality, such as receiving emails without the ability to download attachments, others remain completely offline.
For businesses, this outage has a cascading effect. Teams meetings are delayed, project timelines are disrupted, and employees must scramble for alternative communication methods. In a world increasingly reliant on digital tools for productivity, interruptions like this underscore how dependent we have become on seamless cloud services.
Root Cause and Microsoft’s Response
According to Microsoft, a recent system change caused the outage. The company has deployed a dual-pronged approach to address the issue. A global rollout of a comprehensive fix, and manual restarts of affected machines to expedite service restoration. While Microsoft claims that over 90% of impacted environments have received the fix, reports from users indicate ongoing issues.
