This is not supported but does anyone know how to force OneDrive for Business use UNC paths?
I\'ve spoke with MS and its not on their roadmap and they arent forth coming
It is supported. Same format as it is for SharePoint Online document library mappings. \tenant-my.sharepoint.com\personal\username\Documents Connect as Web Drive: https://tenant-my.sharepoint.com/personal/username/Documents
The option is only hidden in the OneDrive simplified UI. You can even turn it on by adding a normal view to the Documents library and turning the ribbon on from Settings (note that of course open in Explorer only shows in IE).
Open in Explorer from OneDrive
