How to change display name in Outlook 2007

If your e-mail recipients see only part of your name, but you want them to see your full name, you can easily make the change in name which you preferred. The display (below screenshot) may show only part of your name which was entered when you first set up your e-mail account.

To display your full name, edit your name in Account Settings.

1. On the Tools menu, click Account Settings.
2. On the E-mail tab, select your Internet service provider (ISP) account, and then click Change.
3. Under User Information, in the Your Name box, type your name the way you want it to appear to people who receive e-mail messages from you. 

4. Click Next, and then click Finish.
