A Microsoft file hosting and synchronization service.
The most likely cause is a sync problem triggered when the IoT-11 devices try to re-establish the local OneDrive folder and then download everything, not a simple proof that the folder is missing in the cloud. The supported troubleshooting path is:
- Check for sync restrictions first Review the files in System Testing - POS for unsupported conditions such as item count, size, invalid characters, invalid file types, or other sync limitations. A file that violates sync restrictions can stop sync even if it appears to work elsewhere.
- Stop and re-establish sync on the affected IoT-11 devices
If there are many errors, the recommended approach is to start over:
- Right-click the OneDrive icon in the Windows notification area.
- Select Stop syncing a folder...
- Select the affected folder and confirm Stop syncing.
- Start syncing the library again.
- Do not rename the synced folder after sync is established Renaming the synced folder breaks the sync relationship.
- If OneDrive reports it cannot find the folder locally, move the problematic content out and back in
On an affected device:
- Right-click the OneDrive cloud icon.
- Select Close OneDrive.
- In File Explorer, move the file or files suspected of causing the issue to a location outside OneDrive, such as **C:**.
- Start OneDrive again from Start.
- Wait until OneDrive shows Up to date.
- Copy the file or files back into OneDrive.
- Clear cached Office upload data
Cached Office upload data can block SharePoint or OneDrive for work or school sync:
- In the taskbar notification area, find the Microsoft Office Upload Center icon.
- Right-click it and select Settings.
- Select Delete cached files.
- Confirm Delete cached information.
- Repair Office before reinstalling OneDrive Before another uninstall/reinstall attempt, repair Office. This is specifically recommended before uninstalling and reinstalling OneDrive for work or school.
- If only the IoT-11 devices fail after “download all files,” test by removing the largest or newest installer files from the synced folder temporarily A moderator-recommended resolution in a similar case was to move the two largest files out of the OneDrive folder, which resolved the issue. That aligns with the documented guidance to check sync restrictions and problematic files.
- If the issue continues, escalate through the work/school support path For work or school accounts, technical support should go through the organization’s IT helpdesk, service desk, or admin.
Because the failure starts again when all files are forced to download, the strongest supported next step is to inspect the contents of System Testing - POS for restriction/limitation issues and then fully stop and re-sync the library on the IoT-11 devices.
