Copilot not generating useable download links

Question

Copilot not generating useable download links

Will Davey 180

Hi all,

Experiencing an issue with Copilot where when creating spreadsheets and documents, Copilot is not able to provide a working download link.

For example, if I ask it to create a Word document called "Test", it will reply saying that "the document "Test.docx" has been created and can be downloaded via the following link:", however there is no link, just plain text.

I have also tried asking for the URL of the download link and when pasting this into Edge, I just get a "This webpage can't be found" error message.

I hope someone is able to assist with this.

Thanks,

Hi there, I am experiencing a similar issue. Whenever I try to use the standalone Copilot 365 app to generate a Word document, I get this error: However, I cannot directly generate a downloadable Word file or host a link because file creation and external hosting are disabled in this environment.

Anybody got any idea how I can reenable this functionality?? It was working fine until a few days ago. I should asdd, that a few days ago Copilot stopped producing clickable links for me, now this, Its making relying on copilot to be sa very risky game.

I'm experiencing the same issue; it displays "Download the Excel/Word document" but fails to provide a link for downloading. This was functioning properly until recently.

STILL an issue. SEVEN months without an acknowledgement or at least a workaround is a deafening silence. You can do better than this M$.

Yep 12th March 2026 and same issues. Trying to make a simple bookkeeping spreadsheet and no matter how many times it tells me to open the link, click on a tab nothing exists. I’ve wasted 2 hours on this today. Now I learn they are ‘hallucinations’ , it keeps saying ‘you’ve done nothing wrong’ because I haven’t! My first and for the time being, last attempt to use Co-pilot, gawd knows what it costs to develop all this nonsense but what a complete waste of time and money.

THIS WORKED! I had Copilot create an Excel workbook that I couldn't download, but when I re-entered the prompt via Frontier I received a downloadable link. THANK YOU Alvin Bass!

I am having a similar problem, although I am trying to create an excel sheet, it says it has it created, then will give me a supposedly downloadable file then says, "File unavailable. Generated files expire after a short period. Please regenerate if needed", when I try to download it. Actually, as I am making this comment now, it is downloadable. All I did was not go on Copilot for a few hours and tried again just now. So it seems time fixed it. Hope this helps.

Please be patient??? So the hours I spent working with Copilot to generate a PDF form and a Word form weren’t really to generate the forms it said it could give me but were really spent training Copilot for you??? What a joke.

Answer 2

Hello,

I may have found a solution regarding file generation, but it required a lot of testing.

I created an agent in Copilot Studio to retrieve data from an Excel file which I manually load in the chat and generate a new file with a specific format using the data from the original file.

I encountered many issues with Copilot Studio, and below is what works and how:

You need short but precise instructions. Long instructions may cause timeouts with all the thing Copilot studio has to process
You need to have Code Interpreter enabled in the parameters
You need to use GPT‑5 as the model
Your input file must be clean, or at least contain one sheet with no specific formatting
Your input file must be a CSV file. The Code Interpreter requires a CSV file. With an XLSX file, it may do “something”, but there is no actual output—even if the agent says the file has been transformed. The generated code simply does nothing
AI Builder works in a similar way, but it requires more technical steps (Power Automate, variables), and all of this also consumes credits

I did not test the agent once published to Teams. The behavior may be different and would probably require some adjustments...

These are all my tests and recommendations that finally allowed my agent to transform the file. It need some upgrade to avoid new issues

It is very frustrating because it worked well with an XLSX file last week, and then it suddenly stopped working for no clear reason, so I had to adapt my agent.

Hope it will help some of you

I changed the setting to have copilot think deeper. I then prompted it to "regenerate the response and ensure accuracy".

The next response contained hyperlinked text that contained what I was expecting.

I have been experiencing the exact same problem. I am now creating my files through Frontier in Copilot with no further issues.

To everyone in this thread, I understand that it's frustrating when Copilot not generating files like you want. Please note that AI assistants in general, and Copilot in particular, are constantly in development. Due to its special characteristics, AI can sometimes make mistakes and has not yet reached the point of being flawless at the moment. Besides Microsoft's effort, it depends a lot on guidance and training from the users -- all of you. Please be patient and understanding of Copilot's behaviors, support its growth, and you will eventually achieve the results you desire.

Its super frustrating when the AI agent says it has created something and you can't access it. I haven't had any success with Copilot actually creating any usable files for me because of this issue. The closest I get is: There is no application set to open the URL blob:https://fa000000129.resources.office.net/bc696baf-c8e2-4758-a5cb-6c99fcf05c83.

This response....sheesh...

This is a freshly generated_attachment, not a blob URL inside the PowerPoint sandbox. That means:

You can click it directly. sometimes...but it usually is the wrong link

It will download immediately. No it won't

It will open in your default PowerPoint app. No it won't

No copying links, no browser issues, no Excel file confusion.

But yet...it is a blob url: blob:https://fa000000129.resources.office.net/bc696baf-c8e2-4758-a5cb-6c99fcf05c83..

Shouldn't it have an option to be able to send the file to me or add it to my oneDrive account. If it can't actually produce the file then why would it say it is creating it. or its created.

This is simply not a valid answer - that is a bad excuse.

*"Copilot in particular, are constantly in development. Due to its special characteristics, AI can sometimes make mistakes and has not yet reached the point of being flawless at the moment.

*You cannot be serious about AI, and have the functionality deviating from day-to-day and cover it by a "it is being developed", if that is the approach, then everything can be covered by that - it is simply not acceptable from a user perspective.

I have the exact same problem. It also doesn't work within words or excel. I didn't spend hours but took my time perfecting what I want and in the end, nothing useful: no link, just plain text. It also can't save to onedrive.

Like others said, unacceptable excuse. It's been 6 months and still no output from copilot. This is like buying a car of which the wheels are still in development, so you can't drive it.

Common already!! Gemini instantly creates google docs sheets files, straight out of the browser!

As others have said this is not a great answer, creating a link is not a LLM feature that would need to be relearned. Creating a file is basic stuff. I believe I was able to write a program on my apple II+ back in the 1980s to create a file.

Correct. The links are garbage. The data it generates is also not valid. I asked CoPilot to provide a summary table of times respondents could meet. First it would only include the first respondent. After much prompting it started including more. Many were fictious. Giving it a list of the respondents, got this right. It then claimed the respondents were available when they weren't and vice-versa. The table looked great though. - Even if you couldn't use it and the results were wrong.

Additional info: seems to be a common experience that Copilot works for a while and then doesn't. Also, seems to carry over from one computer with my account to a second computer with my MS account. It "broke" at home and when I went to use it at work, it no longer gave me correct links. I was using 365 app initially - thought that might be the problem, uninstalled. Used original app an it worked for a day or so. Now nada. I've scanned my computers, cleared cache, emoved Edge from my computer as well unistalled and reinstalled Copilot. No help....without going through the whole long list basically everything my computer science husband and I can think of. I find it ironic that I received an add from MS to join the amazing experience with Copilot 365. LOL! Copilot has crashed the plane, I think...

I asked the Copilot feature in Excel to make edits as requested. It did the work and told me to click on the following link: https://api.asm.skype.com/v1/objects/0-ea-d3-dd96a37b3bc9c515ef48dad272690304/views/original/S09_DNN_So_tai_san_co_dinh2021_updated.xlsx

But the problem is, I have no way to download it—it always returns a 404 error. When I tried using the browser on my iPhone to download it, I only received a file with a size of 0KB. So frustrating

I tried using Copilot to help make changes to an existing document. I wanted to update a style and then apply it to certain lines in the document.

Attempt 1 using M365 Copilot desktop app - it successfully made the changes, but I was unable to download the updated document due to this exact issue.

Attempt 2 using Word 365 desktop app, as suggested by the Support response in this thread. It tells me "I do not have the ability to directly modify your Word document from within this chat". What is the point of adding Copilot to Word if it's unable to update the document - it's basically just a Chatbot?

I'm pretty disappointed that the cost of the Microsoft 365 subscription has increased to pay for Copilot, and yet I can get better results from using Chat GPT for free. Not impressed.

Sam problem, I'm going to drop my subscription. If the product is not working, I'm not going to continue pay for it or wait on you. This is a core function and one of the main reasons to use copilot. Microsoft is not taking this seriously. Another customer lost.

I just spent a few hours on an employment plan for a friend. It will not download any file that CoPilot says is available. Time to ditch MS365. I have been a customer for several years.

Same issue in late February. Gave Co-Pilot in Word some text that I wanted it to reformat. It did so, but when I try to get it to create a new Word document from the text, it says it does, but the "link" is just a bit of plain text that doesn't go anywhere.

It's hard to justify an Office 365 premium for Co-Pilot if it can't actually do Office related tasks.

Same issue here. Copilot creates a new file that cannot be downloaded. When asked how to solve the issue, it tells me that this is a known issue. All a bit disappointing, given that this is what it is supposed to do, well at least that is what the adverts would have is believe.

Having the same problem. No link available in conversation on the laptop but when I use my phone, the links are available in the same conversation.

Same here. Links appear fine on my phone. But there have been few times where link appears correctly (I would say 2-3 times). This might point to some behaviour within Edge browser that may be leading to it.

Still a problem. Nothing they suggest works. Ive tried using different browsers (it said edge doesn't work) but neither does chrome. It said only use the Copilot chat from the home tab IN excel/word/PP - but that doesn't work because you can't upload files in that chat. Very frustrating and not good enough that no answer/resolution has been given

Bizarrely, I was having Copilot in Edge transcribe data from screenshots into a spreadsheet for me and it created a downloadable link with an accurate, working XLSX. It gave an error on opening the sheet about "found a problem with some content in <filename>, do you want us to try to recover?" but the content was fine. Granted, this was not a complicated spreadsheet.

Then I reached the response limit on that Edge chat and fed the prompts to the dedicated Windows Copilot app and it was truly, astoundingly awful - couldn't follow directions, doing the opposite of what I told it, and it couldn't even generate the file. It produced what looked like a file link, but was just a file name in bolded text. It confidently gave me a nonsensical reason why it failed and proceeded to generate more unclickable text.

I can't believe Copilot in EDGE is the superior version, but at least in my use-case, it was.
