Sign in to your Microsoft Outlook account and click on the “Settings” gear icon in the top right corner of the page.
In the new Settings window Click on "Account" and then "Signatures"
Name and create your Outlook signature
Navigate to the section labeled "+ New Signature." Below that, you'll find a small text box where you should enter a signature name.

Navigate to the bottom of the page and click the drop-down arrow icon to select the signature you want for new messages or replies/forwards. You can also select "No Signature" if you don't want to include it in a message.
That’s how to add a signature in Outlook.com. Don’t forget to click “Save” at the bottom of the page when you’re done. Close the settings window, and your new signature should appear at the bottom of every message you send.

See our full post on other possible fixes when the Outlook signature is not showing.
Signature is not displaying correctly
You’ve learnt how to create email signatures in Outlook, but when you send a message with the signature included, it’s not displayed correctly. In most cases, this is an HTML problem. It’s usually a result of using Microsoft Word to create your signature.
Possible fix: Use Outlook’s built-in editor to create your email signature. Also, stick to standard fonts like Calibri and Arial and avoid excessive formatting.
Images not showing in Outlook signature
You’ve created a professional Outlook signature with a logo and your headshot, but images either don’t load or appear as broken links. Sounds familiar? This issue has several causes, including large image files, incorrect file paths, and HTML code problems.
Possible fixes:
i) Keep your images under 100 kb.
ii) Check to ensure you’re not using a local path (like C:\Users\Name\Pictures\logo.png), otherwise the images won’t show up for recipients. Instead, ensure your images are hosted online or embedded correctly using the “Insert image inline” option.
iii) If you coded the signature yourself, check the code to ensure there are no missing tags or broken references.
