Outlook Express .dbx recovery.

We have a client who has been using Outlook Express for their business email accounts, recently the "Sent" items DB became corrupt and we have tried everything that we can think of to recover the data. We have used close to 15 different tools to attempt a recovery including purchasing DBXpress, sadly every tool we have tried is only able to recover emails prior to 2006 and nothing newer.

Are there any company's out there that will work with the .dbx file itself and perform a repair/recovery on the data?
