Add a signature to messages
In Outlook 2013 and Outlook 2016, you can create personalized signatures for your email messages that include text, images, your electronic business card, a logo, or even an image of your handwritten signature. You can set it up so that signatures can be added automatically to all outgoing messages, or you can choose which messages include a signature.

On the Home tab, click New Email.
On the Message tab, click Signature > Signatures.
Under Choose default signature, in the E-mail account list, click an email account to associate with the signature.
In the New messages list, select the signature that you want to include.
Note To create a signature, under Select signature to edit, click New and type a name for the signature. And then in the Edit signature box, add your signature.
