SYMPTOMS
Consider the following scenario. You create an e-mail message in the Draft folder. You add recipients to the Bcc box in this message. You use a Web Distributed Authoring and Versioning (WebDAV) program to send this message. A recipient of this message uses a third-party MAPI client computer to forward this message to another recipient. In this scenario, the recipient of the forwarded message may be able to see the recipients that you added to the Bcc box when you created the message.
