How MBOX Handles PST Data
Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Mailbox File format supports it. Format-exclusive metadata fields that have no equivalent in Mailbox File are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality PST Outlook Data input produces an excellent Mailbox File output. Since the target format is lossless, output quality matches your input exactly. PST Outlook Data encodes data using mathematical algorithms that preserve every data point. Mailbox File prioritizes exact data preservation. The conversion maps between these approaches intelligently.
Email format conversion from PST Outlook Data to Mailbox File preserves message content, headers, attachments, and folder structure. MIME encoding, embedded images, and HTML body content are maintained. This is critical for email migration between different mail clients and servers.
