You have an Exchange Server 2016 organization.
All users work from a main office and use Microsoft Outlook 2016.
You recently ran the Microsoft Office 365 Hybrid Configuration Wizard and moved most of the user mailboxes
to Exchange Online. A network administrator reports an increase in the amount of outbound SMTP traffic from
the network.
You need to reduce the amount of bandwidth utilization for the outbound SMTP traffic.
What should you do?

      If the MX records still points to on-prem, the email will be send over the internet to Office 365 (Hence additional outgoing mail).

      If you point to the cloud, then this behavior is altered that you have more incoming mail from Office 365.

      As the question provide: Most of the users are in the cloud.

      This will lower the outgoing mail flow, which is the only thing asked at this time. Because the on-premise server doesn’t need to send all the mail for the users to the cloud.

        The key is to “lower the bandwidth utilization” for outbound SMTP. The MX record change reduces the bandwidth as emails for users in the cloud would no longer be sent to on-prem before being routed to the cloud. This would remove the bandwidth used for this in and out traffic, and as such more bandwidth is released for the outbound SMTP traffic and outbound SMTP traffic is also reduced.

      In a Hybrid environment (which is the case for this scenario), you can point the MX record to either on-premise or Exchange Online (O365). Where you point the MX record, will determine where the INBOUND emails from the internet will arrive first.

      Let’s say the MX is pointed to on-premise (as per this question). If an inbound email from the internet is destined for an Exchange Online mailbox, then that email will arrive on-prem first, then be routed from on-prem outbound to Exchange online. This routing involved from on-prem to Exchange online is what the question is asking you to fix, as the outbound SMTP traffic for Exchange Online is too much load the bandwidth.

      Now, keep in mind that if the email destined for the Exchange Online mailbox is replied to, it will go outbound directly from Exchange Online to the internet, as this is the shortest route to the destination. Exchange Online mailboxes does NOT depend on the availability of on-prem Exchange servers for outbound email. The exception to this is if Centralized Transport is used.
