Fix OneNote Email Page Attaching as an MHT File
Question details
The user wants to insert OneNote page content directly into an Outlook email body for editing, but the software attaches the page as an MHT file instead.
- Product
- Microsoft OneNote
- Device & OS
- not provided
- Scenario
- Using the Email Page feature in Microsoft OneNote to share notes via Outlook.
- Observed behavior
- The OneNote page is attached to the Outlook message as an .mht file instead of appearing as editable text within the email body, and repairing OneNote does not resolve it.
Ensure that Microsoft Outlook is set as the default email client in your Windows system settings, as OneNote relies on this specific configuration to export and format page content correctly.
Install the Latest OneNote and Office Updates
Microsoft frequently releases patches for known integration bugs between OneNote and Outlook. Updating your Office suite is the primary fix for the MHT attachment issue.
This issue is often caused by a version mismatch or a specific bug in a previous Office release that disrupts HTML rendering between OneNote and Outlook.
Launch Microsoft OneNote. Click on the 'File' tab in the top-left corner, then select 'Account' from the left-hand menu.
Under the 'Product Information' section, click on the 'Update Options' drop-down button and select 'Update Now'.
Wait for Office to check for and download any available updates. Once the installation is complete, restart your computer and test the 'Email Page' feature again.
Export as Word Document and Copy Manually
If the direct email integration remains temporarily broken, exporting your note to Word provides a reliable workaround to get formatted, editable content into your email.

Frequently Asked Questions
Why does OneNote send an MHT file instead of regular text?
This typically occurs due to a communication error or version mismatch between OneNote and Outlook. When OneNote fails to parse the page content into HTML format for the Outlook email body, it defaults to packaging the entire page layout, text, and images as an MHT web archive file.
What exactly is an MHT file?
An MHT (MIME HTML) file is a single-file web page archive format. It bundles HTML code, images, and other media into one document. OneNote uses this format to preserve the complex layout of your notes when standard text insertion fails.
Can I change a setting to force HTML instead of MHT in OneNote?
No, there is no built-in toggle in OneNote to switch between MHT and HTML for the 'Email Page' feature. The application automatically attempts to use HTML; if it results in an MHT attachment, it indicates a bug or integration failure that usually requires a software update to fix.
