A Microsoft file hosting and synchronization service.
Hello,
If you exceed the OneDrive Cloud Storage limit (5GB), your account will be put into a frozen state.
So, if you upgrade or free up your storage, it usually takes 2-4 hours for the updated storage to be reflected in your account. In some cases, it can take a maximum of 24 hours for the storage to sync.
After 24 hours have passed, open an incognito tab in any web browser and sign in with your Microsoft account here:

Check whether the updated storage is reflected there.
If the storage has synced online but not in the OneDrive desktop app, unlink and relink your Microsoft account in the app.
