Troubleshooting

My ZixMail for Outlook® 2007 plug-in is not displaying when I open Microsoft Outlook®.
How do I set up ZixMail for use with a proxy?
I want to send a BCC of a message.
I forwarded a ZixMail message to someone else, but when they tried to open it, they got an error message.
I received this error message "This message is either not a ZixMail message or it is a ZixMail message wrapped in another encryption protocol."
I received this error message "Cannot connect to the ZixDirectory".
