To obtain a digital ID and add it to your mail account

To send digitally signed messages, you must obtain a digital ID and then add it to your mail account. Outlook Express adds your digital ID to your mail account automatically when you send your first digitally signed message.

  1. Obtain a digital ID from a certification authority.

    Go to Microsoft Internet Explorer Digital ID Web site for links that will take you to a certification authority to obtain a digital ID.

  2. In a new message window, on the Tools menu, click Digitally Sign.
  3. Compose and send your message.
  4. When you send the message, Outlook Express searches your computer for a valid digital ID with the same e-mail address and then adds the ID to your mail account. If more than one valid digital ID is found, you must choose which ID to add to your mail account.
