To remove password from a PST file, it is necessary to know the version of MS Outlook you are dealing with.
The reason behind such statement is that there are some changes made in versions released after MS Outlook 2003. This changes the entire scenario involved in removal of password from a PST file. Thus, steps for password removal will be also different. To remove password from a PST File created in version prior to Outlook 2003, 2007, 2010, or Outlook 2013, you have to follow these steps:
Close MS Outlook and make a copy of PST file you wish to work with.
Run Scanpst.exe on your selected file.
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.
Open the file in Outlook using File menu.
However, if you are working on versions i.e. later than 2003, then you have to follow different process. Such process is as follows: This step wise procedure is specifically for MS Outlook 2010.
Open File > Account Settings > Account Settings.
Account Settings window will pop up. Now, click on Data File > Select the path which shows .pst file extension > Click on Settings
After clicking on “Settings”, a new window will pop up from where you can change the password. Click on ‘Change Password’
Select the password as you wish and click OK
Thus, selection of password removal task entirely depends upon the version of MS Outlook you are using.
