When using Outlook 2010 you have the ability to create an e-mail signature. An e-mail signature will be what appears at the bottom of every e-mail sent from your account. The following documentation will show how to create this signature using Outlook 2010 for Windows.
While creating an e-mail message in Outlook, select Signatures from the Signature drop down menu.
Type a name for your signature in the window that appears and then click OK.
Type in the signature that you wish to appear on your e-mails.
Select your signature options (were you would like the signature to be default) and than click OK.
If you have set your signature as the default, it will automatically be created at the bottom of every message.
If you have not set your signature as the default, you can select your signature by selecting your signature's name form the Signature drop down menu.
