Copilot Immediately Deletes Responses Before Throwing Up, "Something Went Wrong," Error

For context, I'm using a business license of Microsoft through my employer.

Yesterday, I started getting the, "something went wrong error on all my conversations. I'll type something in, Copilot gets to the end of its response, then it suddenly disappears and throws the error. One weird clue is that if I restart my PC, I'll get one answer before the problem persists. The problem happens on browser and the app (in fact, it happens in any Microsoft app with Copilot built in). It happens on my phone's Copilot app. Here's everything I've tried:

  • a new internet connection.
  • restarting my PC.
  • logging out of all my sessions on all devices.
  • clearing cache and cookies.
  • resetting the app from Installed Apps.
  • deleting all recent conversations since the problem started.

Please help.

    Hi everyone,

    This issue is currently recognized as a known service issue in the Microsoft 365 admin center under Issue ID: CW1391746.

    Microsoft has identified this as a service degradation in Microsoft 365 Copilot Chat, where users may receive a “Something went wrong” error when submitting prompts. The root cause has been linked to a recent configuration change affecting token authorization.

    At the time of the latest update, Microsoft is in the process of reverting the change and monitoring the service to ensure recovery.

    As this is a backend service issue, there is no action required from end users at the moment. The recommended approach is to monitor the Service Health Dashboard in the Microsoft 365 admin center for updates.

    Thank you for everyone patience and understanding while Microsoft works toward a resolution. I will share further updates as soon as more information becomes available.

    Hi @Jack Andrew Connell

    I understand how frustrating this is, especially after trying multiple troubleshooting steps with no improvement. You’re not alone in experiencing this many users are currently seeing the same behavior when using Copilot.

    From what you’ve described, this aligns with a known service-side issue affecting Microsoft 365 Copilot Chat. When users submit prompts, the request may fail and return a generic “Something went wrong” error, which prevents normal use of the service.

    To give you a clearer picture, here’s a concise update on the situation:

    • Summary of impact: Users may be unable to successfully submit prompts in Copilot Chat. The service can fail after generating a response, resulting in a “Something went wrong” error. The issue is still under investigation, and no confirmed workaround is available at this time.
    • Impact time: The issue started on June 15, 2026, at approximately 06:12 UTC, and an end time has not yet been determined.
    • Scope of impact: The issue affects Microsoft 365 Copilot Chat. Some users within organizations may experience consistent failures when submitting prompts, while others may not be affected.

    At this time, there isn't a client-side setting or local troubleshooting step that can fully resolve this. The best approach is to monitor updates in the Microsoft 365 Service Health section of the admin center.

    I recommend asking your IT administrator to report the issue through the Microsoft 365 admin center and note that it affects your user experience as this helps ensure the scope of impact is clearly captured

    You and your colleague can also submit feedback directly within Copilot using the Feedback option as well.

    The more users report the same behavior; the more it helps increase visibility and supports further investigation toward a fix.

    As a forum moderator, my role is limited to providing general guidance and basic troubleshooting and I don’t have access to backend systems or the ability to influence or expedite the engineering team’s investigation. I apologize for the inconvenience this has caused and thank you for understanding and feedback.

    The behavior described (Copilot starting to answer, then clearing the reply and showing “Something went wrong”) across multiple apps and devices indicates a service-side or account/licensing problem rather than a local client issue, especially since it briefly works after a reboot and all standard client troubleshooting has already been tried.

    From the available guidance, the next steps are:

    1. Ask the organization’s Microsoft 365 admin to verify the Copilot license and policies
      • Confirm that the account is assigned a license that supports Microsoft 365 Copilot and that the license has fully propagated.
      • Ensure Copilot is not blocked by organizational policies or privacy controls.
      • If device-based licensing or an unsupported update channel (such as Semi-Annual Enterprise Channel) is in use for Microsoft 365 Apps, switch to user-based licensing and a supported channel (Current Channel or Monthly Enterprise Channel).
    2. Have the admin open a support ticket with Microsoft
      • Because the issue reproduces on web, desktop, and mobile, and persists after standard fixes (sign-out, cache clear, app reset, different networks/devices), it matches the type of tenant/account issue that requires escalation by Microsoft support.
      • Admins can reference that Copilot is missing/disabled or not working correctly for a properly licensed user and that all client-side steps have been exhausted.
    3. If Copilot is accessed through Microsoft 365 Apps on the device
      • Ensure the network requirements for Copilot are met and that no security software or network controls are intermittently blocking Copilot endpoints.

    Until Microsoft support or the tenant admin corrects the underlying account or service configuration, the intermittent “Something went wrong” failures will likely continue despite local troubleshooting.

    Hi everyone,

    I would like to share an update regarding the recent issue affecting Microsoft 365 Copilot Chat.

    Based on the latest information, this issue has now been fully resolved. Microsoft has confirmed that the root cause was a code regression that impacted prompt submission. The issue has since been mitigated through a configuration update, and validation with affected users indicates that the service is now functioning normally.

    If you unselect Auto at the top right, and select a specific GPT model, it seems to work.
