PST Files

So what exactly is a .PST file?

The funny thing about PST files is that most people use them, but probably have no idea. PST stands for Personal Storage Table and is used by various Microsoft programs. The main one being Microsoft Outlook.

If you use Outlook for email, all of your data is being stored in a PST file. This includes email, calendars, contacts, notes and more. So you can also imagine what happens if this PST file goes missing or becomes corrupt.

Some information about versions:

Outlook 97

Starting with Microsoft Outlook 97 the Personal Storage file is encoded in ANSI format. It has a maximum file size of 2 GB. If the file exceeds this size it will become corrupted. This format is supported by Microsoft Outlook 97, Outlook 98, Outlook 2000, Outlook 2002, and Outlook 2003 Internet Message Access Protocol Version 4rev1 (IMAP4) accounts and HTTP accounts.

Outlook 2003

Starting with Outlook 2003 the Personal Storage file is encoded in unicode format. It allows a user-definable maximum file size up to 33TB that exceeds the previous limit of 2GB. This format is supported by Microsoft Outlook 2003 and Outlook 2007. A file that is created in the personal folders format in Outlook 2003 or Microsoft Office Outlook 2007 is not compatible with earlier versions of Microsoft Outlook and cannot be opened by using those older versions.

So just remember that PST files are very important. It is also very recommended to make regular backups of your PST files.
