How to reduce the Outlook PST file size?

Facing slow Outlook due to massive PST files? Give the smart Aryson PST Compress Tool a try. It helps reduce PST size by cleaning up excess space and compressing large attachments, while preserving emails, contacts, and folder layouts intact. It even supports password-protected PSTs, and you can compress multiple files in one batch. You can pick between quick and aggressive compression levels and preview the expected disk savings. The tool handles both ANSI and Unicode formats and doesn’t need Outlook installed at all. Furthermore, it offers a handy “auto-optimize” option for future compressions and works consistently with feature upgrades.
