In order to use the Microsoft Whiteboard in the meeting room effectively, users will need to login to their individual Whiteboard Accounts. Microsoft does not provide a method to delete whiteboards if logged in as the room user. It is important that the PC or Quicklaunch is set to prevent the storing of School or Work Accounts as Microsoft provides no programmatic way of deleting them at this time.
