What is ANSI PST Maximum File Size Limit?

MS Outlook is an email application with MS Exchange as its Server. The older versions of Outlook are 2000 and 2002/XP, which have ANSI PST format. New versions are 2003 and 2007, which have UNICODE format. In ANSI format, PST file has maximum limit of 2 GB while in Unicode PST, maximum file size limit is 20 GB.

Cautious Aspects: If ANSI PST File size exceeds beyond 2 GB then, Outlook application can get corrupted. Large sized PST files can hamper the speed of Outlook application which in turn can harm work as application becomes slow.

Consequences of Huge Sized ANSI PST Files: In case you are using Outlook with version 2000 or 2002 for a long period of time and storing all your emails in it, then size of PST files will increase, which can lead to various negative consequences. Some of them are given below:

• Oversized PST Difficult Hamper Outlook Speed: Using Outlook files for a long time leads to large sized PST files, which later on decreases Outlook performance and it becomes difficult to manage them.
• Corruption/Damage Is Possible: Oversized PST files in Outlook can get damaged or corrupted and data loss is likely to occur in that situation. To get rid of corruption, make sure any of your ANSI PST file of Outlook 97, 2000, or 2002/XP does not go beyond 2 GB maximum file size limit.
