A Microsoft file hosting and synchronization service.
Dear @Lima, Lucas,
Thank you for posting your question in the Microsoft Q&A forum.
Based on your description, your OneDrive storage is still full after deleting the SharePoint site.
Here are some suggestions you can try:
Check deleted data is still in the Recycle Bin or not
Go to your SharePoint site > Recycle bin > Empty it
Scroll down >open Second-stage Recycle Bin
Delete everything there as well
Even after deletion storage updates are delayed (not real-time) and it can take 24–72 hours (sometimes longer) for the system to reflect changes
However, deleted files may be kept in a hidden library due to compliance rules, these files still count toward storage even if you don’t see them. If you are user, try to contact your IT admin, only admins can check or remove this.
For reference: Restore deleted items from the site collection recycle bin
I hope information above can help you resolve the issue. Feel free to reach out if you have any other questions.
