There is the most efficient software that I would highly recommend to convert PST to HTML Email Software, which is the Outlook to HTML Converter. It can be applied to convert all those Outlook PST files—including your emails, contacts, tasks, and calendars—into HTML automatically. It then becomes an absolutely compatible time saver because it converts both ANSI and Unicode-based PST files and handles batch conversion. If you can convert corrupted PST files to an HTML format with data still intact due to its recovery mode, this excellent software can even let you view your PST files before conversion is done with its preview function. This tool is compatible with all operating sequence versions on MS Windows; hence the user could find this tool as convenient without any problems during conversion.
