How to Switch between HTML & Plain Text in Outlook
Managing email layouts in Outlook helps ensure your messages look correct upon arrival. This guide walks you through the process.
In New Outlook, click the Settings gear, go to Mail Compose and reply, and choose your message format. In Classic Outlook, go to File Options Mail, then select your format from the dropdown. You can also change the format for a single email via the Format Text tab.
Applies to
This guide covers Classic Outlook, New Outlook for Windows, and Outlook on the Web (OWA). Knowing how to adjust your Outlook message format settings ensures your emails appear properly formatted. Professional newsletters and basic text notes benefit equally from this control.
Why change the email format?
Switching formats keeps design elements intact or strips away unnecessary styling for maximum compatibility.
What happens when you are done?
New messages adopt this layout by default once saved, though previously sent items remain untouched. Signatures containing images or complex styling may look different after updating this preference.
Quick Summary Table
| Format | Best For | Pros | Cons |
|---|---|---|---|
| HTML | Marketing & Business | Visual appeal, branding | Can trigger spam filters |
| Plain Text | Technical & Accessibility | High deliverability, fast | No styling options |
| Rich Text | Internal Exchange | Advanced layout control | Not compatible with all apps |
How to change format in New Outlook for Windows
1. Open the New Outlook app.
2. Click the gear icon for Settings, usually found in the top right corner.
3. Navigate to Mail > Compose and reply.
4. Scroll to Message format and select your preference.
5. Click Save.
How to change format in Classic Outlook
1. Open Classic Outlook.
2. Go to File > Options > Mail.
3. Under 'Compose messages,' use the dropdown menu to select HTML, Plain Text, or Rich Text.

How to change format for a single email
Individual messages require format changes on the fly when global defaults remain unchanged. Message windows feature the Format Text tab in the top ribbon for this exact purpose. Selecting HTML, Plain Text, or Rich Text from the Format group applies the change to that specific draft.
Summary
Managing your Outlook formatting options remains vital for professional communication. Visual power from HTML or reliability from Plain Text both live inside the Compose and reply menu. Additional assistance appears within our guides covering managing email signatures and troubleshooting email delivery.
