2. On the Home tab, click New Email.
3. Select the Insert tab on the ribbon menu.
4. Click the caret icon on the Signature button.
5. When the Signatures and Stationery box opens, click New and give your custom signature a name.
6. The window lets you include your business logo or a professional headshot, format and color text, and create links for texts and icons (via Microsoft).
7. You can pick the email account where the signature appears.
8. Set your preferred signature to load by default on new messages and replies or forwards.
9. Click OK when you’re done.
Your fresh and memorable signature will be automatically added every time you compose a new draft (via Microsoft).
