Microsoft Office Outlook 2007 and Microsoft Office Outlook 2003 supports both American National Standards Institute (ANSI) and UNICODE personal folders (.pst) and offline folder (.ost) files. You can use the following four registry entries to limit the size of both the .pst and the .ost files:
• The MaxFileSize registry entry
• The WarnFileSize registry entry

Thew default values for these entires are:
MaxLargeFileSize = 20 GB
