The Mail settings dialog box appears.
In the Compose Messages section, click the Signatures button.

The New Signature dialog box appears.
Type a name for your new signature.
The name you type appears in the New Signature box. You can name a signature anything you want.
The New Signature dialog box closes.
Type the text of the signature you want in the Edit Signature box, and add any formatting you want. Click OK.
To change the font, size, color, or other text characteristics, use the buttons just above the text box. If you’re more comfortable creating highly formatted text in Microsoft Word, you can create your signature in Word and then select and copy it to the Edit Signature box.

Click the OK button in the Outlook Options window.
The Outlook Options window closes.
Your new signature will now appear on every new message you send. If you create more than one signature, you can switch to a different default signature by following Steps 1 through 3 and then choosing the signature you want from the New Messages menu in the Choose Default Signature section.
If you want to include a signature in your replies and forwards, choose the signature you want from the Replies/Forwards menu in the Choose Default Signature section.
