storage outlook full, deleted everything on onedrive but its not updating my storage space

Deleting OneDrive files does not always update Microsoft storage immediately. While the storage status is still over quota, Outlook.com can block sending and receiving email, and OneDrive files stay read-only.

Try this:

1. Check Microsoft storage usage in the Microsoft storage area of the account dashboard to confirm whether the account is still over the cloud storage quota.
2. In OneDrive, open Manage your OneDrive storage and make sure the Recycle bin is empty. Items in the Recycle Bin still count toward storage.
3. In Outlook.com, go to Settings > Account > Storage and free up mailbox space if needed. Outlook mailbox storage is separate, and consumer mailboxes are limited to 100 GB.
4. Check the Outbox and mailbox storage in Outlook.com, because mailbox content can also prevent mail flow.
5. If storage was just cleared or extra storage was purchased, the updated quota can take up to 24 hours to appear. If it still has not updated after 48 hours, contact support.

Important effects while over quota:

• OneDrive: cannot upload, edit, or sync new files.
• Outlook.com: cannot send or receive email if cloud storage quota or mailbox quota is exceeded.
• After 3 months over the OneDrive limit, the account can be frozen.
• After 6 months, Microsoft might delete the OneDrive and its files.
