A staple of email since its creation has been creating a signature that displays at the bottom of the messages you send. If you’ve recently created a new account in Microsoft’s revamped email service Outlook.com, you’ll want to create a signature for it too.
Log in to your Outlook.com account and click the Settings (gear icon) and select More Mail Settings.
From the Options page click Message Font and Signature under the Writing Email section.
In the Personal Signature box, type in the information you want to include in your signature. You can do basic formatting of the text and include links, but I haven’t found a way to add an image like you can in the desktop version of Outlook. When you’re done remember to click Save.
There you go. Now your signature will appear on all messages you send from Outlook.com.
