  • Open Command Prompt and paste file path to pst19up followed by Enter.
  • The command line will resemble "C:\My Documents\pst19upg.exe" -x outlook.pst.This will create a copy of the PST called "filename.psx"
  • Now, rename the original PST file with different name (as you wish).
  • From Command Prompt, type pst19upg.exe -followed by file name and press enter.
  • Here is your password-free PST file.
  • Run scanpst.exe against recovered PST and Choose repair, if prompted.

If you're using versions beyond 2003, you'll need to adhere to a distinct process. The step-by-step instructions outlined here pertain specifically to MS Outlook 2010.
