How to change your signature block in outlook

Whether your job title has changed or you’d like to update your phone number, Microsoft Outlook makes it super easy to change your email signature’s contents. We’ll show you how to edit your signature in Outlook’s desktop, web, and mobile versions.

Remember that changing the email signature on one device doesn’t affect your other devices. For example, if you update your signature on your mobile, it won’t change your signature on your desktop, and vice versa. To use the same signature across all your devices, you’ll have to update the signature individually on each of your devices.
