Hi Tom, 

Welcome to Box Community and glad to help! 

You may try to reset your Box Drive manually: 

1. Exit Box Drive (if it is running). If necessary, use Task Manager to end the Box.exe process.


2. Ascertain whether any files exist in C:\users\rUSERNAME]\AppData\Local\Box\Box\unsyncedFiles. These are files that have not been uploaded to Box. If these files do exist, and if you want to keep them, copy them to any location outside of C:\users\rUSERNAME]\AppData\Local\Box\Box\ (such as your desktop). Proceeding with the steps below deletes these files.

• You may need to show hidden folders to see \AppData.


• Delete this folder: C:\users\sUSERNAME]\AppData\Local\Box\Box.


• From RegEdit, delete the registry entries under HKEY_CURRENT_USER/Software/Box/Box to clear Box preferences.


• Restart the Box Drive and follow the prompt to log back in.

Once you log back in, please mark your Box folders for offline use. 

Hope it works! 

I had the same problem. Performed all the steps outlined above, and the files which were not accessible offline before are still not accessible. Request assistance.
