Cannot Delete File in One Drive - quota exceeded

Dear @Anggara Pratita,

I hope you’re having a good day. 

Since your OneDrive for Business has exceeded its 5 TB quota and you've already emptied the Recycle Bin, I would first recommend trying to delete files directly from OneDrive on the web rather than through File Explorer or the sync client: https://onedrive.cloud.microsoft/

If the files can be deleted from the web interface, the issue is likely related to the sync client. However, if the files are also read-only in OneDrive on the web, there may be an administrative restriction involved, such as a retention or compliance policy.

In that case, I would recommend contacting your Microsoft 365 administrator and asking them to verify:

• Whether the OneDrive site has exceeded its assigned quota.
• Whether any retention or compliance policies are preventing file deletion.
• Temporarily increase the OneDrive storage allocation, if possible, so that the account can return to a writable state and cleanup can be performed. Your administrator should follow this instruction: Change a specific user's OneDrive storage space - SharePoint in Microsoft 365 | Microsoft Learn

If your administrator has already increased the quota and the problem still persists after some time, they may need to open a Microsoft support case to investigate the OneDrive site's backend status.

If you’re unsure who your administrator is, this article may help: How do I find my Microsoft 365 admin?

I hope this information helps point you in the right direction. If you run into any issues while trying the steps, or if something still doesn’t feel quite right, please don’t hesitate to reach out again. I’ll do my best to support you however I can.   

Looking forward to hearing back from you with any updates or additional details.  

Warm regards,
