Outlook doesn't recognize PST Password once System Crash
A Personal Storage Table (or Personal Folders file) is the data file used to store all your messages, calendar events, and other items in Microsoft Outlook and other Microsoft software (Exchange Client, Windows Messaging).PST format is mostly used in home users or in small organizations. As all the data of Microsoft Outlook is stored in one .PST file on the local computer, you can easily backup or sync your mails.
The .PST format has been increased greatly since the Microsoft Outlook 2003 that provides greater storage capacity (maximum file size 20GB) and Unicode support.
PST files are extremely important for your mails. It's necessary to apply protection on them. However, password protection of PST files is not so secure technically, since there have been tools that can remove or bypass the password protection. Password protection can be used to protect the content of the .PST files.
PST stores the 32 bit CRC32 hash value of the password entered by the user. When a PST file is opened using any version of Outlook it'll check the hash value stored in it. If this hash value is 0 the file will be opened without any password requirements. If it found any other value the enter password dialog will pop up. The problem with CRC32 hash is the fact that a lot of strings can have the same CRC32 hash. This means for a single 32 bit hash value there will be a lot of different but correct passwords! But sometimes, you may watch that Outlook fails to identify the PST password. It generally happens because of two possible reasons: PST password is not correct or is damaged.
The .pst file format is fundamentally insecure for multiple reasons. First, the password (actually a weak (without the first and last XOR) CRC-32 integer representation of it) is simply stored in the .pst file, and Outlook checks to make sure that it matches the user-specified password and refuses to operate if there is no match. But the actual data is still there.
Second, Microsoft (MS) offers three values for the encryption setting: none, compressible, and high. None encryption is easy because the .pst file contains data in plaintext, and a simple text editor will show the contents.
Compressible encryption is a simple byte-substitution cipher with a fixed substitution table. Of course, since the table is fixed, it is also widely known. Attackers can simply decipher the data and see the computer's plaintext.
High (sometimes called "better") encryption is similar to a WWII German Enigma cipher with three fixed rotors, which are widely known. If the key, which is the value of an internal identifier, is known, attackers can simply decipher the data and see the computer's plaintext.
In all such cases, PST Password Recovery tools come to solve the problem.
