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.
