How to change your signature in Outlook

Ending a message with your signature adds a professional touch to your email communication. It's an easy way to provide recipients with your contact information, showcase your personal brand (or that of your employer), and, most importantly, subtly reassure recipients that the email is authentic.




Basically every email service, including Microsoft Outlook, offers a way to add a custom signature. Sometimes you may want to change the signature in your Outlook email because your job title has changed, there are new contact details, you have new branding, or for some other reason. Fortunately, Outlook on all platforms, including web, desktop, or phone app, offers a straightforward way to do this. This guide will show you how to do it.

You need to change the Outlook signature separately in the desktop and smartphone apps. If you change the signature on one device, it will not be changed on another.
