Large PST Files and Problems in Earlier Outlook Versions: In the earlier versions of MS Outlook (2000, XP/2002 and earlier versions), the email data is stored in files with ANSI PST format, which has the maximum file storage space limitation of 2 GB for personal folders (.PST files). Once the PST files reach or go beyond this value, they are not supported by the application and this leads to corruption.
Large PST Files and Problems in Newer Outlook Versions: Though, this storage space limitation no more exists in the later versions of Outlook (which have 20 GB maximum Unicode PST file size limit), but in these versions, higher file size affects Outlook performance and leads to data management issues. Such issues are required to be taken care of.
Error – The File Has Reached Its Maximum Size: Suppose you have been using Outlook 2002 for a long period of time. You are constantly receiving mail messages and storing other mailbox items in a single PST file (default PST file) while overlooking the fact that this practice of yours can further lead to serious complications and issues. As you go along with this practice, a point comes which exemplifies the problems for you. When you attempt to save an Outlook item (say an appointment or a contact or task), you fail t do so. Additionally, what you see on your screen is an error message stating:
The file file_name has reached its maximum size. To reduce the amount of data in this file, select some items that you no longer need, then permanently (shift + del) delete them.”
This error that pops up, tells you that your PST file has grown to its maximum value (2 GB) and more items cannot be accepted. The above-mentioned error message is received when MS Office XP Service Pack 1 is installed. On installing the service pack for Outlook 2002, the application is caused to stop storing more data after the PST file reaches to 1.82 GB size. This also serves as prevention against Outlook application corruption, which normally occurs when PST file goes above 2 GB.

To serve this purpose and to solve the file has reached its maximum size error; some split PST software is the option.
