Copilot Notebooks chat and file creation
I'm having the same issue. I'm using Copilot Notebooks on the Microsoft 365 Copilot home page and every file it creates for me is saved to:
sandbox:/mnt/data/ [filename]
I still haven't found a solution other than going directly to PPT or Word and entering the prompt, or worse, switching to ChatGPT, which I don't want to do because I need everything organized within my M365 Copilot account.

As of today, this issue has resolved for me—files are now saving and accessible as expected. I didn’t change anything on my end, so I’m not sure what fixed it.
At the time I submitting my post, I couldn’t access those files from my M365 environment.
Another twist...during a recent client Copilot training session with a leadership team, 1 out of 12 executives (from the same company) experienced the same "sandbox" link issue, while the rest could access their Copilot-generated files normally. All 12 were using the same IT configuration, which makes this even more puzzling.
📣 Questions for the community:
- Has anyone else seen this issue resolve on its own?
- If you’ve found a specific fix or explanation, could you share it?
- Could this be a permissions or sync issue that only affects certain accounts?
Appreciate any insights—especially for those supporting teams where only a few users are affected.

Lucky you! I'm still trapped in sandbox-land.
GRRRRRRR.

Lucky you! Unfortunately for us, my boss still (yesterday, 10th July) can't get out of the sandbox!

still experiencing the issue, was the file path updated to something other than 'sandbox'?

We are experiencing the same issue. Works fine in the chats, but gives the 'sandbox' url in the Notebooks. Would anyone know whether this is a bug and if there is an active support ticket?
