If you're using data from an older Outlook version (such as Outlook 2002 or earlier), your PST file will be in ANSI format. The biggest drawback of ANSI PST is its 2GB size limit. This limit can cause the file to become corrupted quickly and cause it to not work properly in newer Outlook versions. Therefore, converting an ANSI PST to a Unicode PST file is essential for better performance and larger file size support.
