How to add a new signature in Outlook
1. Open Outlook and then click "New Email" in the ribbon bar to create a blank email message.
2. In the untitled email message, go to the ribbon bar. Click "Signature" and then "Signatures…."
3. In the Signatures and Stationary window, click "New."
4. Type a name for the new signature and click "OK." If this is your first signature, you might want to name it something like "default."
5. Enter and format the signature in the text box. You can choose the font and text size, insert links and images, and even insert a digital business card from Outlook's address book.
6. At the top right of the Signatures and Stationary window, you can choose which signature you would like to use by default with each of your email accounts, and if you want the signature to appear in email replies, or only in original messages.
7. Click "OK" to save your changes.
