You can use OSTTOPSTAPP ANSI to Unicode Converter as an option. This tool is very secure. Microsoft Outlook stores email messages, contacts, tasks, notes, events, and attachments in ANSI PST files. The ANSI PST format, which has a 2 GB capacity limit, has been around since the early versions of Outlook. However, Microsoft released the Unicode PST format, which has a far bigger size limit of 20 GB and allows more characters, with the release of Outlook 2003 and later versions. Moreover, the file size is now infinite. All Windows OS versions can be installed without difficulty, and because the software is user-friendly, anyone can use it.
