We are running Outlook 2000 on a Windows 2000 pc using Exchange 5.5. When an email is addressed to three people, various people are dropped into the CC portion of the email or deleted entirely when the email is sent. Also, today an email was sent to one person, and three other people were cc'd. The email went to the three cc'd people, but when we went to sent items, the TO person had been dropped off entirely. Has anyone every heard of this happening?
