Microsoft Outlook 2002 and earlier versions limit the size of Personal Folders file to 2GB. Whenever the PST file exceeds that limit, you will not be able to open or load any more data in it. This is called oversized PST file problem. Outlook has no built in way to rescue the oversized PST file that is inaccessible. But Microsoft provides an external tool pst2gb as a makeshift which can restore the file to usable status. But this tool fails for some cases in restoring the oversize files.
MS Outlook stores your all email messages and other mailbox items in an Outlook data file which is known as PST or Personal Storage Table. MS Outlook has two types of PST files which are ANSI PST and Unicode PST. ANSI PST is used in earlier versions of MS Outlook 2002 and is a default file format of these Outlook versions. It has a limit of 2G and when it exceeds its limit, then the file becomes corrupted and the same problem happens with Unicode PST file. Unicode PST is used in later version of MS Outlook 2003 and is default file format of these Outlook versions which has a limit of 20 GB.
The corruption of Unicode PST file are very rare because of the maximum size but it can be corrupted it the size exceeds that limit. If the corruption occurs then you can lose all your important emails and other mailbox items which are saved in the file. In that moment, you can split your oversized PST file into various parts so that you can avoid the file to be corrupted.
