If the goal is to delete the Excel file itself from Microsoft 365 on the web, the Delete option is available from the file’s More options (...) menu on the Microsoft 365 home page under Quick access or My Content. If the file is in a shared location such as a SharePoint folder, select Go to file location and complete the deletion there.
If the file is stored in a SharePoint document library, the delete command is in the library toolbar:
- Open the SharePoint document library.
- Select the file by clicking the circle/checkmark area, not the file name.
- Select Delete on the toolbar.
- Confirm Delete.
If the file is in OneDrive, select the file or folder on the OneDrive website and choose Delete from the top bar or the right-click menu.
If Delete still does not appear, the supported causes in this scenario are:
- The file is not owned by the current account.
- The file is currently being edited.
- There is no permission to delete that file or folder.
- The item is checked out to another user.
- A retention policy or retention label is preventing deletion.
About storage: if the file cannot be deleted, it remains in its storage location. Also, after deleting files from OneDrive and the OneDrive recycle bin, there can be a short delay before storage availability updates.
