Is it possible to "go back" in a Powerpoint presentation and view slides that  
  
have been deleted or originals of chaged slides?  
  
Concretely, is this a security issue, where a someone might get the  
  
presentation and find earlier confidential materials buried in it?

As long as you have "Fast Saves" turned OFF, there is no archiving of edited  
  
items in the file.

Hi!  
  
Although you say your boss is worried about being able to restore  
  
history, there should be an additonal concern. There might be  
  
confidential data in the presentation that is not obvious, and which  
  
might be missed out during a cleaning attempt.  
  
Things that come to mind are: VBA code, unused master slides, notes,  
  
text that is off the slide, data stored in shape tags, custom data  
  
fields, names of items (accessible via VBA), items covered up by other  
  
items...  
  
Converting to PDF is probably a good safety step to ensure that things  
  
like these don't get left in.

Just to play devil's advocate:  
  
How do you know this?  You've no way of retrieving edited content from a normal  
  
presentation, so how can you tell that it's not carried over when you insert  
  
slides from the presentation into another one?  
  
I'm not trying to be difficult, but if the boss wants rigorous proof, you have  
  
to apply rigorous methods of testing.  ;-)
