Important This article contains information that shows you how to help lower security settings or how to turn off security features on a computer. You can make these changes to work around a specific problem. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this workaround in your particular environment. If you implement this workaround, take any appropriate additional steps to help protect your system.



SYMPTOMS
When you type the name of a contact in the To box in a Microsoft Outlook Express e-mail message, the e-mail address does not resolve to the name that you type. This problem occurs even though the contact is in the Address Book. When this problem occurs, the auto-complete feature successfully completes the contact name. However, the send operation fails because the address is not specified.



CAUSE
This problem may occur if the following conditions are true:
 * You are using Outlook Express on a computer that is running Microsoft Windows XP with Service Pack 2 (SP2).
 * The Locked Down registry entry is set to disable Outlook Express identity switching on the computer.



WORKAROUND
Warning This workaround may make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We do not recommend this workaround but are providing this information so that you can implement this workaround at your own discretion. Use this workaround at your own risk.

To work around this issue, change the Locked Down registry entry to enable identity switching on the computer. To do this, follow these steps:  Click Start, click Run, type regedit in the Open box, and then click OK. Locate and then click the following registry subkey:

 

 Right-click Locked Down, and then click Modify. In the Value data box, type 0, and then click OK. Exit Registry Editor.</ol>
