A Microsoft file hosting and synchronization service.
Dear @PAWAR Amitkumar,
I hope you’re having a good day.
Thank you for your question.
I noticed the AI response has already suggested several possible causes, including storage quota, permissions, Office activation, and library settings. Those are all valid possibilities. However, before jumping into advanced troubleshooting, I think it would be helpful to narrow down the scope of the issue first.
Could you please confirm the following?
- Does this happen with all files in your OneDrive, or only specific files?
- Are you opening the files from OneDrive on the web or from File Explorer / Office desktop applications?
- Are you able to create a new file in OneDrive?
- Do you see any specific message other than "Read-only"?
- Is this a OneDrive for Business account provided by your organization?
One point mentioned in the AI response is particularly worth checking: if the entire OneDrive site has become read-only due to a storage quota issue, it can affect all files, even for the owner. Likewise, an expired license or a permission change can result in similar behavior. Before investigating those possibilities further, it would be helpful to understand whether the issue affects all content or only certain files.
Once you provide the answers to the questions above, we can better determine whether this is related to:
- OneDrive permissions,
- OneDrive storage quota,
- Microsoft 365 licensing,
- Office desktop applications,
- or a specific file/library configuration.
I look forward to your update.
Please understand that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can work together to find a solution.
Warm regards,
