Consider the following scenario.

• On a computer that is running Windows Vista, you configure Microsoft Office Outlook 2007 to use a digital signature when you send e-mail.
• You import a digital ID into Outlook 2007.
• The digital ID includes a Cryptography Next Generation (CNG) key.

In this scenario, the Request For Permission to Use a Key dialog box appears whenever you try to send an e-mail message. After you grant Outlook 2007 permission to use the digital ID, Outlook 2007 successfully sends the e-mail message.

Note: When you try to send the e-mail message, you may also be prompted to enter the password of the digital ID. This situation depends on the security level that you specify for the digital ID.
