OneDrive for Business – Known Folder Sync fails

September 26, 2018

When activating Known Folder Sync in OD4B the sync never starts due to folders that cannot be synced.
These folders are Junction folders on the drive and needs to be deleted.

First do a dir in the users document folder and look for hidden files like this:
C:\Users\USER\Documents>dir /ah
Volume in drive C is Windows
Volume Serial Number is 903B-D31E

Directory of C:\Users\USER\Documents

18.04.2018 10.10 2 230 Default.rdp
26.09.2018 11.59 402 desktop.ini
26.09.2018 11.59 Intern video [C:\Users\USER\Videos]
26.09.2018 11.59 Min musikk [C:\Users\USER\Music]
26.09.2018 11.59 Mine bilder [C:\Users\USER\Pictures]
2 File(s) 2 632 bytes
3 Dir(s) 55 879 593 984 bytes free

Then delete the junctions like this:

C:\Users\ÙSER\Documents>rmdir “Intern video”
C:\Users\ÙSER\Documents>rmdir “Min musikk”
C:\Users\ÙSER\Documents>rmdir “Mine bilder”

Other files in conflict with the sync needs to be removed from the local machine before the cloud sync can start. Backup and move the files in case of future needs.

Happy OneDriving.
