Why doesn't Offline Files work?

Question

Windows

Good afternoon!
Colleagues, we have roaming profiles and Folder Redirection enabled at our enterprise.
At the same time, offline files are disabled on the PC and everything suits everyone, but one laptop has appeared on which you need to have an offline copy of the files. The profiles folder is configured according to the instructions https://technet.microsoft.com/en-us/library/jj6490... When you enable offline files, the error " The
process cannot access the file because this file is occupied by another process"
what could be the reason?
