A Microsoft file hosting and synchronization service.
Dear Мане Рохан Сампат,
Good day! Thanks for posting in Microsoft Community. We are happy to help you.
According to your description, I would like to reconfirm if you have tried to empty the OneDrive recycle bin and the Second-stage recycle bin (at the bottom of Recycle bin page). If not, please go to OneDrive for Web (go to www.office.com and click the OneDrive icon), then empty recycle bin.
If you have already emptied the OneDrive recycle bin while the error message still pops on when you delete OneDrive files, you need to contact your admin/IT department. They have the related permission to help you to increase your OneDrive storage and resolve this situation.
We look forward to your response. Thanks for your cooperation.
Sincerely,
George | Microsoft Community Moderator
