Outlook instructions

Adding the Outlook HTML Signature

With this method, it will show in your Signature drop-down list. Before you start, I’d suggest making sure your HTML template file renders properly in the browser. If it doesn’t show correctly in a browser, it will most likely fail in an email. In the example below, I’ve used Google Chrome to open my .htm file.

You may have noticed that I referenced a .HTM file and not .HTML. It seems odd since we call them HTML signatures, but Microsoft Outlook will only render the .HTM file. If you load a .HTML file, you’ll never see the HTML email signature. Your web browser doesn’t care and will display either file.

  1. Rename your email signature file if needed. Outlook will use the portion before the .htm as the email signature name.
  2. Test your .htm file in a browser.
  3. From the File menu, select Options.

  1. From the Outlook Options dialog, click Mail.

  1. On the right side, press CTRL and click the Signatures… button.

This will open the apps folder that contains your Microsoft Outlook signatures. Usually, it is the appdata\roaming\microsoft\signatures folder.

  1. Copy your .htm file into this folder.
  2. Make sure your Compose messages in this format: shows as HTML.
  3. Close the folder and return to Outlook Options.
  4. Click OK.

Your newly added HTML email signature should show in your Signature drop-down list. You should go to Outlook’s Signatures and Stationery dialog and make sure you’ve assigned this to the proper account and if it should apply to new messages as well as replies and forwards.
