Large PST files often create performance issues in Outlook and make manual backup processes slow and unreliable. Copying or exporting such files can result in incomplete backups or further corruption. SysInfo PST File Recovery simplifies this process by allowing users to backup Outlook PST files without any file size limitations. The tool scans the PST file thoroughly and displays a preview of mailbox items before saving, ensuring data accuracy. This preview feature helps users confirm that all emails, attachments, and folders are intact before creating the backup. Compared to manual methods, this controlled and verified backup process significantly reduces the chances of data loss and provides peace of mind for users handling extensive Outlook mailboxes.
