Lost Pst Password-remove Or Recover It

When MS Outlook is used to receive confidential and business important mails, PST (Personal Storage Table) password protection feature can add to its data security. Unlike other email client information files, PST is the single file that centrally stores all email messages, contacts, notes, calendar entries etc. So, it becomes quite convenient to access the data. We can set a password to avoid external intrusion. The PST password may get lost or forgotten. This is the time when PST Password Recovery is required. Also due to a drawback of PST upgrading utility - pst19upg.exe, it is also possible to remove PST password in such cases.

Removing PST Password

In order to make PST compatible with Outlook’s later versions, Microsoft provides a utility called pst19upg.exe. The process requires free space of about three times the size of the original PST. The file should be backed up first and scanned using scanpst.exe. Then pst19upg.exe can be used on file through command prompt as:

"C:My Documentspst19upg.exe" -x outlook.pst.

Note: pst19upg.exe full path may vary

A copy of PST is created but with extension .psx. We can then rename the original PST and use "C:My Documentspst19upg.exe"-i filename.psx to get the password free PST. We can scan it and open it in Outlook for use. The utility has two basic limitations: It doesn’t support Unicode format of Outlook 2003 and 2007 and secondly, it may fail in several cases.
