This article describes a workaround that allows adding images to a signature in Outlook Web App.

By default, OWA does not support adding images to signatures. Entering HTML code does not work either since it is not automatically recognized. Follow the steps below to add an image to your signature.

Note: The image should be accessible on the Web and have a URL which can be used to bring it up in a browser.

  1. Open the image you want to add in a browser window (Internet Explorer is used in the example). 
  2. Right-click the image and choose Copy.

  3. Open OWA and go to Options > Settings > Mail to edit your signature.
  4. Use Ctrl+V to paste the image you copied since context menu is not available. Check the box for automatic signature addition if needed.

  5. If automatic addition is disabled, add your signature to a new message using Insert > Your Signature.
