SharingItem.CC Property (Outlook)
Returns a String representing the display list of carbon copy (CC) names for a SharingItem. Read/write.
This property contains only the display names, delimited by semicolon (;) characters. The Recipients collection should be used to modify the CC recipients.
If the SharingItem uses an Exchange sharing context, then setting this property to any value other than Nothing prevents the item from being sent and causes the Send method to raise an error.
