Remove password or protection from encrypted personal storage PST file

As technology advances, we are available with more options which in turn help in making our work more secure and safe. While using Outlook, the data security is kept in mind and is paid proper attention. Hence when you try to create a new personal folder in Outlook, you are provided with three different kinds of encryption.

First one is No encryption which directly means that no password will be set for the folder. Second is the default setting of Compressible encryption. Third is called High encryption (Outlook 2003 and higher versions) and Best encryption (Outlook 2002 and lower versions). Both of these encryption set password which you have to type in order to access your files in the respective folder.

Once if you miss out or forget your password, you no longer have the access to your PST files as well as to other important data. In order to deal with such situation you can either remove the password of the file that had been forgotten by you or decrypt the data of the file. To remove the password of the file, you can use the utility ‘pst19upg.exe’ which had been released by Microsoft years ago.

The utility pst19ups.exe was aimed at upgrading older versions of PST file. The only side effect of it was that it removed the passwords of the PST file. The side effect of that issue could serve help in this matter. Follow these steps in order to remove the password from the file:

  • Make a copy of the file whose password you have forgotten to work upon it.
  • Run Inbox Repair Tool (scanpst.exe) on the copy of the file created by you. If it asks for Repair, go ahead without using the backup option as you are already working on a copy.
  • Go to the command prompt and type the following command ‘C:\My Documents\pst19upg.exe –x filename.pst’ which denotes the path where the file is stored and name of the file. Now press Enter. A copy of the file will be created with ‘filename.psx’ where name of the file will be same as the original one.
  • Rename the original file name.
  • Again go to command prompt and now type ‘C:\My Documents\pst19upg.exe –i filename.psx’ and then press enter.
  • With this a password free PST file will be created from psx file.
  • Again run scanpst.exe on the file and if asks for Repair, go ahead and repair the file.

Note: This utility works only on the ANSI files which are created using Outlook 2002 and older versions. Hence it cannot be used for removing passwords from Unicode supported PST files of Outlook 2003 and older versions.

For Outlook 2003 and older versions the only way left is to decrypt the data from the respective file in the original format. This is a professional tool which is advised to be used by everyone in order to recover the data from the password-protected or encrypted PST files without any necessary need of technical expertise.
