Offline Icon

  <--- This symbol appears in the system tray (lower right corner of screen) when your computer has gone "offline."

It indicates that you are not connected to the network. Once the network connection has been restored, it appears with a small letter "i" on it in order to indicate that files need to be synchronized.

Double-click on the icon to bring up the notification box. Then click OK to reconnect to the network and synchronize.
