There are a couple of ways that you can add an image to your email signature that will be accessible to all through alternative text. The easiest way to do it is through online Office 365 Outlook, but you can also do it through the desktop version of Outlook. If you use both the online version and the desktop version, unfortunately, you will need to recreate the signature in both programs as it doesn’t carry over.
