If you are using Outlook 2007, here are some basic instructions for how you can add these icons to your signature.
1. Open Outlook
2. Click on Tools
3. Click on Options
4. From the tabs, click on “Mail Format”
5. Click on Signatures
6. Click on the New Button
7. Give your signature a name (Company name will do)
8. Then in the Edit Signature section, type out everything you want included in the signature. My signature has my name, title, logo, address, phone, email, web address and Twitter/Facebook icons.
9. To add the images to your signature (we have attached the Facebook/Twitter icons to this post for you to save and use in your own signature) click on the “picture” icon (which is the 2nd icon from the right)
10. After you click on Picture, a browse wizard will pop-up and will allow you to browse your hard drive and add your twitter/Facebook icons to the signature.
11. Once you have the images in the signature, click on one of the images to highlight it. Then click on the “hyperlink” button (it should be the last button on the right)
12. In the address field at the bottom of the hyperlink window, type in your Twitter or Facebook address (depending on which image you are linking)
13. Click ok
14. Repeat that until you have all your images linked to the right web addresses.
