MS Outlook, be it the earlier versions like Outlook 2002 and 2003 or the later versions like Outlook XP, 2007 and 2010, stores all its information it the form of a single PST file. PST (Personal Storage Table) file with the name Outlook.PST is located in the local hard drive of a system. This PST file is used for storing all the composed, sent and received emails along with the created calendar events, tasks, schedules, notes, etc. PST file is the local repository for storing all the user mailbox items irrelevant of the account one is using like POP3, IMAP or HTTP.

With the emails and other mailbox items accumulated in the PST file, it can grow well beyond the defined size limit. Once this happens, chances of PST files getting corrupt increases, which leads to loss of data. Earlier versions of MS Outlook put a size limitation of 2 GB on the file size; however the later version like MS Outlook 2007 and 2010 allow the file size to go up to 10 GB. Overloading the files beyond the defined limit poses problems while retrieving or accessing the emails and eventually depreciates the performance of Outlook.

Other reasons that cause PST corruption are abrupt system shutdown, software malfunction, network connection failure, data storage device failure, hard disk failure, PST header corruption and MS Outlook failure. The best possible way of dealing with Outlook PST corruption issue is to have a backup copy of the file. One can also rely on the Outlook PST repair tool offered by Microsoft called the Inbox Repair Tool (ScanPST.exe) and the PST2GB Truncation Tool. Both these tools have their set of limitation. While scanspt.exe is only suitable for resolving minor corruption problems, PST2GB is likely to chop off important data from the file in order to reduce its size.
