This guide contains common Box Sync issues and what to do if files are not syncing.
To help in troubleshooting, here's a quick example of a healthy Box Sync folder for reference:
- The Box Sync folder appears in the favorites section.
- If the Box Sync folder is not here, make sure you have Box Sync installed and that is it installed on a local native drive (not a network or external drive). It will be on a local native drive by default.
- Files and folders with blue check mark icons indicate successful syncing.
- On Windows, if there are no icons, you may be logged out of Box Sync.
- If there are yellow icons, Box Sync is scanning your folder tree and/or syncing your content.
Mac - Yellow icon
Windows - Yellow icon
- If there are red icons, there was an error syncing that item.
- The Box icon appears in the system tray/menu bar to indicate that Box Sync is running and you are logged in.
- On Windows this is a blue Box, on Macs it is a black "b".
- If the Box icon is gray (gray "b" on mac), make sure you are logged in to Box Sync.
- If the icon is not there, try restarting Box Sync from the Start Menu or Spotlight Search.
