Digitally Signing an E-mail Message with Outlook 2000, Outlook 98, Outlook Express, Netscape, and Eudora Pro 4.1

With Microsoft Outlook 2000, Outlook 98, Outlook Express, and Eudora Pro 4.1, you can digitally sign your outgoing e-mail messages.

Signing a message does not affect contents of the message or protect the message from being intercepted and read by someone other than the intended recipient. To ensure that only the intended recipient can read the message, you must also encrypt the message. If the recipient of a signed message does not use an S/MIME-enabled e-mail package, that person can still read the message-your digital signature simply shows up as an attachment.

The Signed icon indicates that a message has been signed. When you receive a signed message, the icon appears in the upper right corner of the message.

You can sign individual messages or configure your e-mail security options to automatically sign all of the e-mail messages you send. For information on selecting the certificate to use when signing messages, see Choosing a Default Certificate for Signing and Encrypting Messages.

Choosing a Default Certificate for Signing and Encrypting Messages

(See instructions on viewing information about a certificate.)
