Hi,
Unfortunately it is not currently possible to preview the contents of a deleted PST file. Your only option is to purchase the program, save the pst and the try and open it with outlook.
If the pst file is corrupt, there are some options. You can run SCANPST.exe, a Microsoft program located on all Windows comptuers and also Recover My Email for Outlook, from
www.recover-my-email.com.
If the file is corrupt or cannot be opened, please contact support via
www.recovermyfiles.com and explain the situation.
