Outlook PST repair Tool

A pst looks like it needs repairing however the pst file is 5 GB large. Everytime I click ok to fix the pst file after it does the CRC check, it crashed. Is there anyway to reduce the size of the PST file so the repair tool  wont crash?

First you can try

scanpst at support.microsoft.com/kb/287497

If that failed, then you can try

Advanced Outlook Repair at http://www.datanumen.com/aor/

Some other options can be found at http://www.datanumen.com/aor/compare.htm but if the above two don't work, the the others will not, neither.
Doesn't Outlook 2003 have a 20G limit on .PST file size?

Another approach is to rename the PST file, open Outlook, have it create a new one, then import from the other.
The computer will take some time to do this with such a large file, but it may succeed.

I'm curious about how this relates to Exchange 2007.  What is the connection?
