automatically track email to team

I have some teams set up in Dynamics online with their own mailbox which is shared with the members of this team. When a team member sends an email using the team email address as the 'from' address the email gets tracked in CRM. When the contact replies to the email, the email goes to the team mailbox but IS NOT recorded in CRM.

How can we configure Dynamics 365 to automatically track all emails sent to a team email account?

Thanks
