New workspace user not getting share status

New workspace user not getting share status

I have added a new user to a workspace and invited them to join the workspace, but they cannot access the documents in the sub folders
 
I added them as a new user, selected them in the invite dialogue and followed the email link back.
 
The invitation email link  takes the user to the folder listing b ut on drilling down, the access error below is displayed
 
Oops! this document is not shared to you, there could be two possibilities:
  • Either the Author canceled the document sharing.
  • Or the Author might have deleted the document.
I can manually share an individual document from a subfolder in the workspace ok, but not the whole workspace it seems.
 
The workspace properties/sharing tab shows the user with a Viewer status.
 
any ideas?
 
cheers
