Hi,
Thanks for your patience and reaching out Microsoft community.
The “Unknown render failure” you’re seeing in OneDrive, both on the browser and desktop app, point to a service-side issue rather than something on your device. This has been affecting Microsoft 365 Family accounts recently due to backend disruptions, even for active subscriptions.
You can try clearing your browser cache, using an incognito window, or switching to another browser. If you’re on the desktop app, reset OneDrive by running
%localappdata%\Microsoft\OneDrive\onedrive.exe /reset
then restart and sign in again. It’s also worth checking the Microsoft Service Status page: https://status.cloud.microsoft.
If the problem continues, Please let me know how it goes.
Regards,
Edward
