A Microsoft file hosting and synchronization service.
Hi, thanks for the update.
Please try to sign in to onedrive.live.com or portal.office.com using the work and school account and confirm whether OneDrive opens there. If the web version also fails, the account needs review by the Microsoft 365 admin for license assignment and OneDrive service status.
If you manage the account yourself, contact Microsoft Support while signed in with the work and school account so the backend account and service connection get checked.
