OL2002: Messages That Are Sent from a Hotmail Account Do Not Support Digital Signatures

When you send a digitally signed message from a Hotmail account in Outlook 2002, the received message appears to be a clear text signed message even though the clear text option was not specified in Outlook 2002.

This behavior occurs because Hotmail does not support digitally signed messages.

To resolve this behavior, turn off the option to digitally sign the message. To do this on a per-message basis, click Options on the View menu, click the Security Settings button, and then click to clear the Add digital signature to this message option.
