To export Yahoo Mail emails to different file formats or email clients, SysInfo Yahoo Backup Tool provides a simple and reliable solution. The software allows users to export Yahoo to CSV and multiple file formats, including PST, PDF, MBOX, EML, MSG, DOC, and DOCX. This makes it easier to open and manage mailbox data across multiple email clients and document applications. Apart from file format conversion, the tool also enables direct migration of Yahoo Mail to email clients like Office 365, Gmail, G Suite, and IMAP accounts. It maintains the complete folder hierarchy, including Inbox, Sent, Drafts, and custom folders, during the export process. All email properties, such as To, From, CC, BCC, Subject, Date, and attachments, are preserved without any data loss. It also includes an option to remove duplicate emails based on different criteria. Users can split large PST files into smaller sizes in MB or GB for better file management. Additionally, there is a Skip Previously Migrated Emails option to prevent duplication if the process is interrupted. The tool supports single as well as multiple Yahoo accounts and runs smoothly on all Windows and mac OS.
