What is a Personal Storage Table (.pst)?

PST FAQsMS Outlook uses an Outlook data file, which is known as PST (Personal Storage Table) to store messages and other mailbox information. There are two formats of .pst files (ANSI PST and Unicode PST). Outlook 2002 and earlier use ANSI as encoding for the PST. This format has a maximum size of 2 GB and does not support Unicode. A files exceeding this size is likely to give errors or become corrupted.

Outlook 2003 and onward uses Unicode and they can store data up to 20 GB. MS Outlook 2010 can store up to 50 GB. A PST file can easily exceed its size-limit by receiving unlimited emails along with heavy attachments. An oversized PST file can cause various problems, such as poor performance of MS Outlook, the oversized file is usually corrupted, Outlook application can shut down while trying to open an oversized PST file etc. The main reason of Outlook’s abnormal behaviour is an oversized PST file.

How can hardware problems corrupt a PST file?

Hardware reasons:

There are three types of hardware issues which can corrupt or damage your PST files:

– Data Storage Device Failure. In case your hard disk has some bad sectors and these particular files are stored on this disk. You will probably be able to read only part of this data or your information will be incomplete and/or full of errors.

– Faulty Networking Device. If the Outlook PST files are stored on the Network server and you try to access it via network links from a client computer. If any of the devices constituting the network (e.g. network interface cards, cables, routers, hubs etc.) link have problems, then the remote access to the PST file may make it corrupted.

– Power failure. If a power failure occurs when you are accessing a PST file, that may leave this file damaged.

There are various techniques to avoid or minimize the PST file corruption due to hardware issues, for example, UPS can minimize the power failure problems, and using reliable hardware devices can also reduce the chances of data corruption.

Software reasons:

– Incorrect file system recovery. A file system recovery may cause PST file corruptions when your file system is broken. If you try to use a data recovery tool or an expert to restore the files on it, they may still appear corrupted, due to the following reasons:

  • Due to the file system disaster, some parts of the original file may have been lost permanently, or overwritten by garbage data, which makes the final PST file incomplete or contain incorrect data.
  • Not enough expertise by a recovery tool or expert may have collected only incomplete or incorrect PST files. Not containing the valid data makes them totally useless.
  • *Using bad/untrusted tools/experts will make the situation worse instead of better, so if you decide to do that, be careful with the choice of products and experts.

– Virus or other Malicious Software. Many viruses can infect your Outlook PST files and make them inaccessible. In order to avoid that, make sure that you install quality anti-virus product to protect your email system.

One of the most unpleasant forms of malware now is the ‘HowDecrypt’ virus that converts your files. It attacks your computer and seriously limits or totally disables its functions by encrypting your files. It will attempt to export money from you by offering a quick and guaranteed solution.

Usually ransomware messages are incredibly realistic looking and are designed to cause alarm and panic as possible – hence the term scareware. Keep in mind that all of these viruses will try to convince you to pay a certain amount in regards to resolve your issue.

– Terminate Outlook Abnormally. If Outlook is shut down abnormally when you are accessing or opening the PST file, then the file is prone to corrupted or damaged. This can happen if a power failure occurs, if you terminate it through the ‘Windows Task Manager’ or if you turn off your computer without quitting Outlook and Windows normally.

– Deficiencies in Outlook programs. As we previously mentioned the early versions of Outlook has a maximum size of PST files up to 2 GB, then they enlarged it to 20 and the latest one is with 50 GB. Nowadays this limit can be reached very easily, which makes the possibility of corrupted PST files even higher.
