Hi Will Davey,
Welcome to Microsoft Q&A!
Sorry for the late reply, I'm just assigned with this. Thank you for reporting the issue, and I understand how inconvenient it is when Copilot does not generate usable download links when creating documents or spreadsheets. It's been a while, so I hope your issue is solved by now.
In case it's not, here are some suggestions on the situation: If you're using Copilot in Microsoft Edge, it's now not supporting actual file creation, but only "hallucinations" of the files. While it can no longer generate or share downloadable samples directly, it can still provide detailed instructions and guidance to help you create them yourself.
If you want to generate files, use Copilot in Microsoft 365 Desktop Apps:
- Open Word or Excel > Use Copilot from the Home tab
- Ask it to create a document or spreadsheet
- Save the file manually or check OneDrive for autosaved versions
Copilot may try to save files to OneDrive, so make sure it is signed in and syncing. You can check your OneDrive > Documents folder for generated files.
Let me know if you'd like help verifying your Copilot environment or any other issues. We’re here to help ensure Copilot works as expected. Thanks for your time.
