Working with audio files in Copilot
Copilot tells me it can work with several types of audio files, but when I try to attach one to a prompt, it says it isn't a supported file type. I've tried MP4, MP3 and WAV files. My intention is to create a transcript from the file. Copilot simply won't do it. Am I doing something wrong, or is there a trick to get this to work?
Neither Microsoft 365 Copilot nor Microsoft 365 Copilot Chat do support today Audio Files. The response is a hallucination of Copilot. Check out the supported filetypes here: https://support.microsoft.com/en-us/topic/file-upload-in-microsoft-copilot-8b7bf432-9576-4b16-9dee-6c19a4169e62

Thanks for the post!
I did see an update from Microsoft that CAD, ZIP, and MP4 will be added at some point soon. I will have to wait! Thanks.
While there's no official announcement explicitly stating CAD, ZIP, and MP4 files will be added to Microsoft Copilot, it's likely that support for these formats will be expanded in the future.

Hello! I was trying to do that earlier in the week and found this post, which confirmed that Copilot does not (yet) have the ability to transcribe audio files directly:

I didn't run across that post when researching. The additions were mentioned in the Microsoft Admin Center > Message Center, but it looks like it's scheduled for August '25. I'm just glad it's coming! I posted the link to the update in my reply to Ankur_B above. This link doesn't give much detail, but here's the summary from the Message Center:
Summary
Microsoft 365 Copilot Chat will support new file types like CAD, ZIP, and MP4 for search grounding, enhancing response relevance. The rollout begins late August 2025, completing by mid-September. No user interface changes; feature is on by default and requires eligible Microsoft 365 Copilot Chat licenses.
