Question : Weird OUTLOOK PST corruption

I'm at a complete loss here.  I've typically always been able to recover corrupt pst files, one way or another.  This time however, nothing seems to be working.  I need some help with this, as there are very important emails that need to be retrieved.

I have the original corrupt pst stored safely, while I work with duplicates.  It was a 2007 office install, and the pst file is about 790MB.

- I initially attempted to use scanpst on the same system with office 2007 installed, but it would stop at stage 6 of 8, saying it made an error and no changes have been made to the pst file.
- I made a copy of the pst, and tried doing the same thing using a different system with outlook 2010 installed, it completed the task, but said the file had 2 folders and 0 files!?!  I still tried to fix it, and absolutely nothing shows up in outlook, although file is still 790MB.
- I used a whole bunch of different utilities on both the "fixed with 2010 scanpst" copy and a copy of the original, but at most I get 6 emails to 54 emails recovered.
- Advanced Outlook Recovery by DataNumen (which I just paid 280$ to get the full version) says it can retrieve 500 items, but they're mostly empty objects, some are ok.

I'm trying to figure a way to recover a "deleted" or "replaced" version of the PST since it synchronizes with the profile on the server when the user logs on and off.  Although, so far no luck.
