If you have a large Outlook PST file, splitting it into smaller parts can make email storage, backup, and archiving easier. A dedicated PST split tool can divide the file by size, date range, year, or folder without requiring you to move emails manually.
For Windows users, the MailsDaddy PST Split Tool is designed to split oversized PST files into smaller files while retaining emails, attachments, metadata, and folder structure. It supports ANSI and Unicode PST formats and works without requiring Microsoft Outlook to be installed. This can be useful when managing large email archives or organizing PST files for future use.
Before splitting, make a backup of your original PST file. Afterward, verify the smaller files to ensure your important emails and folders are accessible.
