What is Microsoft Copilot? AI tool integral to Word, Excel, and Teams goes down in major outage - what has firm said
Copilot, Microsoft’s AI assistant, has been hit by a major outage.
The system can be used in its own but is also integrated into the company’s other apps. The outage, flagged on the official Microsoft 365 Status X account, has raised concerns among businesses that rely on AI-driven productivity tools.
Copilot is Microsoft’s artificial intelligence assistant. Copilot is integral to Microsoft 365 apps like Word, Excel, and Teams.
On its website Microsoft Copilot says: “Microsoft Copilot is your companion to inform, entertain and inspire. Get advice, feedback and straightforward answers. Try Copilot now.”
The tool has gone down for users this morning. Customers have reported that they have been met with the message: 'Sorry, I wasn't able to respond to that, is there something else I can help with?'.


Microsoft said in a post on X: "Upon an initial investigation, we've identified this issue may impact any user within the United Kingdom, or Europe, attempting to access Microsoft Copilot.
“Indications from service monitoring telemetry suggest an unexpected increase in traffic has resulted in impact. We're continuing to investigate further to determine the next steps required”.
