We appreciate your understanding that sometimes the initial suggestions may not resolve the problem very soon. However, we can work together to narrow down and resolve the situation. For further clarity on the issue could you please try the below:
- Could you please try to Open the Document Library where the folder is located> At the bottom left, Return to Classic SharePoint> Select the folder and try to delete folder again
- Could you please Right-click on the affected folder> Move to> My Files> Move here. Check your OneDrive for Business and try to delete the folder from there.
