OneDrive Shows 6.5 GB Used Despite Empty Storage | Storage Management Issues

An empty OneDrive file list does not necessarily mean your Microsoft cloud-storage usage is zero. Microsoft includes Outlook.com pictures and attachments, plus other personal Microsoft-app content, in that allowance. Exceeding either cloud or mailbox storage can stop Outlook.com sending and receiving, so rebuilding the desktop Outlook profile will not correct a server-side quota problem. Since Manage Storage fails even in private browsing, try the Microsoft account dashboard’s Microsoft storage breakdown and Outlook’s Email storage view; the Outlook mobile app can also refresh storage information under Settings > your account > Storage. Check large attachments, including Sent Items, before removing anything. If you recently deleted content, Microsoft says quota updates can take up to 24 hours. If usage remains unexplained or those views also fail, use Get Help > Contact Support for OneDrive/account storage. Provide the 6.5-GB figure, rendering error, deletion time and screenshots privately, and request an account-specific storage investigation.
