Managing a large Outlook PST file can become difficult when the file grows too large, Outlook performance slows down, or you need to organize email data for migration and backup. A practical solution is to split the PST file into smaller, manageable parts based on size, date, year, folder, sender, subject, or other criteria.
Shefware PST Split Tool is designed to simplify this process while maintaining the original Outlook email hierarchy and metadata.
