Add yourself to your Contacts list in Outlook 2007 so you can create a Business Card to send as an attachment to all your outgoing emails.
Once you have added yourself as a contact, choose Tools > Options > Mail Format > Signatures and chose the signature to attach the card to or create a new one.
Click New if creating a new card, and from the Business Card dropdown list, choose your Contact entry to attach it as a business card to each outgoing message.
Is there a way that you can add the business card signatures WITHOUT also having it as an attachment to your e-mail???
