The user needs to replace placeholder images in an existing EMLTP email template, similar to the workflow available for OFT and MSG files.

How to Replace Embedded Images in an EMLTP Email Template

Product: Email Client
Device & OS: not provided
Scenario: Modifying an existing email template saved in the EMLTP format to update its embedded placeholder images for a new campaign or message.
Observed behavior: The system does not support directly replacing embedded images within an EMLTP file, requiring the user to find a workaround.

Before you start

Before proceeding, ensure you have access to the original HTML source code of your email template, as directly editing the EMLTP file is not supported.

Solution 1Recommended

Edit the Original HTML Source File

Since EMLTP files cannot be edited directly to replace images, the best approach is to modify the source HTML file before generating the email template.

By modifying the underlying HTML code, you can easily swap out the image URLs or file paths before exporting the final template to your email client.

Open the HTML file

Right-click your original HTML email template file and open it using a code editor or a standard text editor like Notepad.

Locate the image tags

Search for the <img> tags in the code that represent the placeholder images you want to replace.

Update the image source

Modify the 'src' attribute within the <img> tag to point to the URL or local file path of your new image.

Save and regenerate

Save the changes to the HTML file, then import it back into your email client to generate your updated template.

Feedback to Microsoft: If you require native support for EMLTP image replacement, consider submitting a feature request through the Microsoft feedback portal.

Solution 2

Use Supported Template Formats (OFT or MSG)

Switching your workflow to use OFT or MSG file formats allows for seamless embedded image replacement directly within the email client.

Frequently Asked Questions

What is an EMLTP file?

An EMLTP file is an email template format used to store message layouts and content. Unlike more dynamic formats like OFT, its structure restricts direct editing of embedded assets such as images once the file has been generated.

Can I convert an EMLTP file to an OFT file?

Direct conversion from EMLTP to OFT is typically not supported natively. To transition formats, open the EMLTP file, copy its content into a new email message in Outlook, and use the 'Save As' function to save it as an Outlook Template (.oft).

Why can't I replace images in EMLTP files directly?

The EMLTP format encodes embedded images and placeholder data in a way that prevents straightforward swap-outs through the user interface. You must edit the source file, such as the original HTML, or use a more flexible template format like MSG or OFT.
