Users who are now moving from MS Outlook 2002 towards MS Outlook 2003 and 2007 might face some problems to export the mailbox items. Microsoft Outlook 2002 and its earlier versions had their PST files were in the ANSI format (American National Standards Institute) with a 2GB maximum file size.

With the release of Outlook 2003 and 2007, the standard format changed to Unicode format with 20 GB maximum file size to avoid file corruptions. With such advancements, older versions of the applications become non-compatible with newer versions and do not open the PST file of Outlook 2000/2002 in Outlook 2003 and outlook 2007. This results in an error as – “Properties for this information service must be defined prior to use”. And even the Import/Export feature in the latest Outlook versions is not helpful to import old ANSI format PST files to it.
