About Adding Workspaces to the Navigation Pane
For easy access to workspaces, you can add them to the Navigate tab in the Workspaces section of the navigation pane. You can add workspaces that you own and those that other users have shared with you.
When you no longer need a workspace in the navigation, you can remove it. When you remove a workspace from the navigation, it is not deleted; the workspace is simply no longer listed in the navigation pane.
You can organize and group the workspaces in your navigation pane by creating workspace folders, and then adding the workspaces to your custom folders.
