Hi, I'm receiving the same exact error on  Win 10 PC. My use case is another user had DropBox, and had >90 GB of files in their C:\users\dropbox   folder. File thumbnails show up with an X in the lower left hand corner. I have reset NTFS permissions to everyone\full control, disabled inheritance, applied to sub-folders. I uninstalled and reinstalled DropBox desktop App, still no access. I'm an IT Pro with a decade plus of experience, so can provide additional technical details if necessary.

Hi schnugee, is this a grey X you're seeing as the sync icon? Do you have OneDrive currently installed and running on your machine?

    Thank you for the response Jay. I see no indications from the Registry that OneDrive was enabled, or used by this user.

      Are the files marked as available offline, or online-only?

        Unfortunately, I don't have the previous user's credentials to log into their profile, or DropBox account. I am the local administrator of the machine, and have full NTFS permissions to the directory.
