Agent Mode continuously loading

Hi all,

I installed Excel Labs today and have tried to use https://www.microsoft.com/en-us/microsoft-365/blog/2025/09/29/vibe-working-introducing-agent-mode-and-office-agent-in-microsoft-365-copilot/ for Excel in the web. However, no matter which prompt I use, it just loads continuously, even when left for hours.

The example above is taken directly from the Agent Mode blog post.

Has anyone got this working? Or know how to resolve this?

I appreciate it's a Preview feature, so happy to wait if it's a temporary glitch, but thought it'd be worth checking.

    That's not a preview feature. That's experimental feature provided as it is outside main Excel. Not necessary it'll be improved and/or ever appears in Excel as built-in functionality.

    Concrete question you may ask directly Excel Labs team here microsoft/Excel-Labs, sometimes they answer.  I'd recommend first to check ReadMe and other issues, if nothing useful open your own issue.

      Thanks Sergei, I wasn't aware of that Github page (it's not linked to from any of the Agent Mode articles/docs). I've logged the issue there.

    Two days later and it's still the same. I can see evidence on Reddit that it is working for some users. Does anyone have any ideas or do I need to log a support ticket?

    Probably everyone on this side of the universe is trying to test 'agent mode' right now.

    And the servers can't handle it.
