Closing a Workspace 
When necessary, a workspace manager can close the workspace. Once closed, the workspace is no longer displayed in the Workspace Directory or in search results and cannot be accessed by workspace members.
You are the owner of the workspace.
At the top of the workspace screen, choose
(Workspace settings).
Open the General Properties tab.
Choose Close Workspace.
Specify a reason for closing the workspace, and choose Close Workspace.
The workspace is closed and a screen appears displaying the workspace details. An e-mail notification is sent to the workspace managers and owner. To return to the Workspace Directory, choose Go to Workspace Directory.
A closed workspace can be reopened, or deleted permanently, by a workspace system administrator.
