2 Utilities to Remove PST password


Some time back, the Microsoft Corporation had released this utility called the pst19upg.exe for upgrading old Personal Folders’ PST files versions for making them work with newer versions. However, one side effect that came with this was that this removed passwords from PST files. So if a user had put a password on his PST file and forgotten that password somehow, then he can make use of this particular utility for removing that password so as to get the access to his mail back. This However does not work will PST files that were being created in MS Outlook versions including Outlook 2003 version, Outlook 2007, 2010 version, or MS Outlook 2013 version. pst19upg.exe utility tend to work only with old PST files (ANSI format) that are being used by MS Outlook 2002 version and other older versions, but does not work well with the new PST Unicode format, that is available in MS Outlook 2003 versions and other ones newer to this.


ScanPST gets installed whenever a user installs MS Outlook program. This utility must be there under Program files in the MS Office folder. The location usually is C:\Program Files\Microsoft Office\OfficeXX (XX being the version no.) or the user can even make use of the MS Windows Search for finding this utility. If this manual method fails to deliver results or if the user has forgotten his password on some Unicode format PST, then, commercial password-cracker programs are needed.

Important Tip

Ensure the availability of good amount of free space as both these utilities need space of around three times the size of that PST to be worked with.
