Ending a message with your signature adds a professional touch to email communication. It easily offers your contact details to the receivers, displays your personal brand (or the one you work for), and, most importantly, subtly ensures receivers that the email is authentic.

Essentially every email service, including Microsoft Outlook, provides a way to add a custom signature. Sometimes, you may want to modify the signature in your Outlook email due to a change in job title, new contact details, re-branding, or some other reason. Thankfully, Outlook provides a straightforward way to do so on all platforms, including web, desktop, or phone app. This guide will provide you with steps for how to do that.
