Microsoft Teams encountered a file-sharing outage caused by recent backend changes, leading to disruptions for users. The issues began during US business hours, with failed attachments and downloads. Microsoft quickly acknowledged the problem, identified the backend modification as the source, and rolled back the change to restore functionality. This incident follows other recent backend failures impacting Microsoft 365 Family subscriptions and Outlook. While not all users were affected, the disruptions raised concerns regarding the company's change management procedures.
"Microsoft has suffered a run of backend changes affecting functionality recently, leading to multiple outages. We need to enhance our detection and response to similar events."
