A Microsoft file hosting and synchronization service.
We get error 0x80070185 across our entire organisation. New user profiles for 300 staff is not really feasible. Nothing fixes it, even running insider versions of OneDrive, Office 365 Click to Run and fully updated Windows 10. Microsoft support were incredibly painful to work with and did not resolve the problem. In fact they would simply do remote sessions and perform the exact same troubleshooting steps each day, until I got fed up.
The issue is specifically with SharePoint Online synced libraries and on-demand files enabled. This feature is a must, so turning off is not an option.
I do suspect it may be related to libraries over the 5000 list view threshold and wonder if anyone else can correlate this?
