Our first indication that something was awry with Outlook was on Downdetector, which noted a sharp rise in reports of service outages for Outlook. Microsoft 365, Microsoft Store, Microsoft Copilot, Microsoft Teams, OneDrive, and Microsoft Azure.
It’s worth noting that users report these issues to Downdetector. Microsoft has yet to comment or confirm any of this.
We’ve contacted Microsoft for comment and will update this live blog when they reply.
