This article provides a step-by-step guide on creating an email signature in Microsoft Outlook. You can design your signature across three Outlook platforms: online, mobile app, and desktop software included in Office 365. Once the basic signature is created, you can customize it to make it visually appealing.
Steps
On the website

Open Outlook. Visit https://www.outlook.com/ using your computer's web browser. This will open your inbox if you're already logged into Outlook.
- If you're not logged in, enter your Microsoft email address (or phone number) and password to sign in.



Click on Options below the selection list.

Scroll down and click on Email signature under the Layout section in the left-hand menu.
- You may need to click on Layout first to expand the options and reveal the Email signature section.

Enter your signature. Type your signature content into the input box on the right side of the screen.

Ensure your signature is always displayed. Check the box labeled "Automatically include my signature on new messages I compose" to ensure all new emails will have your signature at the bottom by default.
- You can also check the box "Automatically include my signature on messages I forward or reply to" to add your signature to every email you send.

Click Save at the top left of the Email Signature section. This will save your changes and add the signature to your Outlook emails.
