MSG Translator

Upload a .msg file, choose the target language, and receive a completely translated .msg that preserves every aspect of the original message—including the subject line, the plain‑text and HTML bodies, all attachments, recipient lists, custom headers, flags, categories, and any other MAPI properties. The translation process begins with a format‑aware reader that uses Aspose.Email’s MAPI engine to extract only the textual components needed for translation, leaving the binary parts such as embedded images and attached documents untouched. These extracted text segments are then fed to a multilingual AI model that has been specifically instructed to retain the original HTML tags, style attributes, and structural elements, ensuring that the visual layout of the email remains identical after translation. The AI’s output is validated against a strict JSON schema to guarantee that the Subject, Body, and HtmlBody fields are present, correctly formatted, and free of malformed markup. Once validated, the translated content is written back into a new .msg file using Aspose.Email’s write‑back capabilities, which re‑inject the translated strings into the appropriate fields while preserving the Unicode encoding of the file. No re‑encoding or alteration of attachments occurs, so any PDFs, images, spreadsheets, or other files remain exactly as they were in the source message. The final .msg file can be opened in Microsoft Outlook, Outlook Web Access, or any other MSG‑compatible email client, and it will display the translated content with the same spacing, fonts, links, and inline images as the original, giving recipients a seamless reading experience in their preferred language. This solution is ideal for international teams that rely on Outlook for daily communication, for legal and compliance professionals who need to review email content across language barriers without compromising evidential integrity, and for support or sales departments that must translate client‑submitted .msg files while keeping all contextual information intact. Additionally, the tool supports batch processing, allowing users to upload multiple .msg files at once and receive a zip archive of translated messages, further streamlining workflows that involve large volumes of email correspondence. By combining advanced AI translation with meticulous MAPI‑aware handling, the service ensures both linguistic accuracy and technical fidelity, eliminating the need for manual copy‑and‑paste, re‑formatting, or re‑attachment of files, and delivering a reliable, high‑quality translation experience for every Outlook .msg file.
