1. 1. Windows 10 computer is unable to sync the files and gives details Access is denied . If I select Offline files and View your offline files, I do see that on a server are the files that the SYNC is trying to sync with. The sync is trying to sync with another user folders. Offline folders somehow has got the wrong folders to sync with. What determine what folders offline files selects to sync with and how can the office files be made to forgot the other user folders.
2. Windows 10 computer show lots of files in conflict that were suppose to be changed while the computer was offline but the computer was not offline. These can be cleared temporarily. What would be a permanent fix.
