The Microsoft PST file extension stands for personal storage. As with all early Microsoft file extensions like DOC, the underlying purpose of the file type is fairly simple to ascertain. What one may not be aware of is that the Microsoft PST file is actually a simple database. As with any database it has scripting to create tables. The tables are actually the data in text or other recognizable language specifying the parameters of your message. The Microsoft Outlook PST file can be rather large in size with some versions allowing up to 20 GB of storage space.
Imagine then the possibilities for failure if the access tables for this huge amount of storage were to be corrupted? And because very often Windows users have set Microsoft Outlook to start up when their PC does, this particular program is made susceptible to corruption and damage resulting in file loss due to improper shut down or start up. When this happens and you may be certain that if you use Microsoft Outlook on a regular basis it will happen, you will need a program specifically designed to recover Outlook PST file information. These programs will repair the PST file, restore your Microsoft Outlook inbox to operation level and allow you to recover Outlook emails.
