Outlook98 corrupt pst files not fixed wi

We have several corrupt pst files that I have run scanpst.exe on. Although the program finds errors and says that it corrects them, the actual messages are not being recovered. I have one file that is 78MB, but only contains empty folders. Is there any 3rd party software available that may be able to recover these messages?

We also have pst files with passwords assigned to them that the users have forgotten. Are there any freeware programs that will strip the passwords from these files?
