First time you open Outlook, you are met with an onboarding flow which enables you to personalize the information in your email signatures.
When you create a new email, your default signature is added automatically. You can have more than one signature, and you can replace the signature in your email with a different one by choosing from the Signature drop-down. The button can be found in the Message tab.
Edit personal information
The information in your email signatures can be edited any time you want. The button Edit Signature can be found in the Home tab in the ribbon. Or if you are composing a new email, you can find it in the Message tab. This will open a dialogue box where you can edit your personal information.
