Can I send Adaptive / Actionable Cards in a message to a shared mailbox?

According to Microsoft, adaptive or actionable cards must be sent to an individual and not a group.  In addition, the recipient must have an account with or Exchange Online.  Since a shared mailbox is treated as a group, Adaptive Cards are not currently supported for a shared mailbox.
