Check and Manage Storage Usage on OneDrive.com

Use the web interface to view exactly what is consuming your OneDrive storage quota, including hidden Outlook attachments.

Hidden storage issues in OneDrive are frequently caused by Outlook or Hotmail email attachments that share the same cloud storage quota. Identifying and deleting these hidden files through the web portal is the most effective way to restore your account access.

Frequently Asked Questions

Why do Outlook email attachments count toward my OneDrive storage?

Microsoft recently updated its storage policy so that Outlook.com email attachments and inline images are now saved in your OneDrive storage, meaning they share the exact same cloud quota as your files.

Can I delete files from OneDrive without deleting them from my computer?

Yes, if you disable OneDrive sync for specific folders or unlink your PC entirely, you can delete files from the cloud via OneDrive.com without removing the local copies stored on your computer's hard drive.

How long does it take for OneDrive to update my storage after I delete files?

It usually takes a few minutes for the storage quota to update after you empty the recycle bin. In some cases, depending on server synchronization, it might take up to 24 hours to fully reflect the freed space.
