Building and customizing solutions using Microsoft 365 Copilot APIs and tools
Dear @MACKOLISKY Thaniah-EXT,
I hope you’re having a good day and thank you for taking the time to share what you’re seeing.
The message you’re encountering “Something went wrong. Try again.” is a generic error returned by Microsoft 365 Copilot Chat when the service is unable to process a prompt request. Under normal conditions this might point to a temporary interruption, but in your case, it aligns with a broader issue that is currently being investigated.
- At the moment, there is an ongoing service-side incident affecting Microsoft 365 Copilot Chat, where users are intermittently or consistently unable to submit prompts. When a prompt is sent, the request fails before the service can process it, and the system falls back to this generic error message.
- The issue began on June 15, 2026 at 06:12 UTC and is still ongoing, with Microsoft actively collecting diagnostics and working toward a resolution.
- Current indications suggest that the impact is partial (affecting a subset of users), which explains why it may appear to work for some users but not others.
I also wanted to reassure you that you’re not the only one experiencing this, I’m currently seeing the same behavior on my side as well. Based on this, there’s nothing in your configuration, device, or account that needs to be corrected locally. The issue is coming from the service itself rather than anything you’ve done.
While waiting for the fix, it can still be worth trying again after some time, or testing from another browser or device just to confirm the behavior remains consistent, but realistically the resolution will come from Microsoft’s backend once the incident is addressed.
One important step that can help move things forward is to inform your IT administrator (if you’re using a work account) and ask them to report the issue through the Microsoft 365 Admin Center, either by checking Service Health or raising a support ticket. This allows Microsoft to correlate affected tenants, better understand the scope, and prioritize the investigation accordingly.
In addition, if you have access to feedback options in your app, submitting feedback directly from Copilot or the Office app (with a short description and timestamp) can also help provide useful signals to the product team.
I really hope this helps clarify what’s going on and gives you some reassurance. As mentioned, this is already under active investigation, and hopefully we’ll see it fully resolved soon. I’ll continue to keep an eye on it and will update you here if there are any meaningful changes.
If this information was helpful, you may consider marking the answer as accepted, this helps make the thread more visible so others running into the same issue can quickly find useful guidance.
Thank you again, and wishing you a smooth and productive week ahead
Warm regards,
