Copilot Not Working

Microsoft has not published a restoration estimate; an active Microsoft 365 service degradation is affecting connectivity to multiple services, so the Copilot and Outlook failures may be part of the same incident.^1^

Check incident progress

• Public status: Monitor Microsoft’s unauthenticated service-status page for general updates.^2^
• Business or enterprise tenant: An administrator should open Microsoft 365 admin center → Health → Service health → Active issues Microsoft is working on. Open the relevant Copilot, Microsoft 365, or Exchange Online incident to see tenant-specific impact, Microsoft’s latest update, and any restoration estimate once one is available.^3^
• If the admin center is inaccessible, continue using the public status page.

There is currently no confirmed “back by” time. Avoid reinstalling or reconfiguring Copilot while the incident remains active; retest after Microsoft marks it resolved. If Copilot still fails after resolution while Outlook and other Microsoft 365 services work normally, the issue should then be treated as a separate client, account, or licensing problem.
