Convert Outlook Email to HTML

Classic Outlook can save Outlook email as HTML, but one message at a time and without attachments. New Outlook has no HTML option at all, and a batch needs another route. Below are three ways to convert Outlook email to HTML, with real user problems and clear limits.

How to convert Outlook email to HTML in classic Outlook?

Open a message, select File, then Save As, and choose HTML as file type to convert Outlook email to HTML. Classic Outlook saves one message per file.

1. Select a message in classic Outlook, or double-click it to open it in its own window.
2. Select File, then Save As.
3. Open Save as type and choose HTML. Choose MHT files if you want text and images in one file.
4. Select a folder, name your file and select Save.
5. Repeat to save Outlook email as HTML for every message you want.

HTML and MHT appear only for messages written in HTML or Rich Text, so a plain text message shows neither. Menu names change between Outlook versions, so check them on screen. Catch: when you save Outlook email as HTML, Outlook keeps a message body, addresses, dates and links, but no attachments. HTML also arrives with extra files and a folder that hold images and styling, so keep them together or your message loses its look. To save a message with its attachments, see how to save Outlook email as PDF.

Can new Outlook and Outlook on the web convert email to HTML?

No. New Outlook for Windows and Outlook on the web save EML or MSG files, not HTML. To convert Outlook email to HTML from new Outlook, save a message as EML first, then convert that file to HTML.

1. In new Outlook, open a message, select three dots (More actions) and select Save as.
2. Choose EML or MSG, then select Save. Files land in Documents by default.
3. In Outlook on the web, right-click a message, select Download, then Download as EML.
4. Convert saved EML files to HTML. See how to convert EML to HTML.

Microsoft Q&A users hit this limit hard. A user asked in May 2023 how to save Outlook email from new Outlook, and a Microsoft moderator replied that it did not save MSG or EML files yet and advised switching back to classic Outlook. Later commenters in 2025 said right-click, Save As now works for EML and MSG, though several reported garbled files in 2023. Switch to classic Outlook with toggle at top right when you need to convert Outlook email to HTML.

How to send new Outlook email in HTML format?

Select File, Options, Mail and set Compose messages in this format to HTML. That setting changes new messages only and does not convert Outlook email to HTML after you receive it.

1. Open Outlook and select File, then Options.
2. Select Mail. Under Compose messages, open the Compose messages in this format menu.
3. Choose HTML and select OK.
4. For one message only, open a new message, select Format Text and choose HTML.

HTML is Outlook's default, and it keeps fonts, colors, lists and pictures. Plain text drops formatting and Rich Text suits Exchange users. Messages sent outside an Exchange organization go out as HTML anyway. Old messages stay in their original format, so use classic Save As or software to export old Outlook email to HTML.
