A Microsoft file hosting and synchronization service.
Hello,
Could you please confirm whether the 1 TB of storage is correctly reflected in your Microsoft account on OneDrive Online?
Open an InPrivate window and sign in to your Microsoft account here: https://onedrive.live.com/?v=managestorage
Please let me know whether your account shows 1 TB of storage online or if it has been reduced to 5 GB.
If the problem is specifically on the OneDrive desktop app,
- Unlink your Microsoft Account from OneDrive and then sign in again to resync your Storage.
- To unlink: Right-click the OneDrive icon on the taskbar, select Settings > Accounts > Unlink this PC.
