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?
A.
From the Exchange Server organization, create a Receive connector that uses the IP address of Exchange
Online as a remote range.
B.
From the public DNS zone, modify the MX record to point to Exchange Online.
C.
From the public DNS zone, modify the SRV record to point to Exchange Online.
D.
From the Exchange Server organization, create a Send connector that uses Exchange Online as an SMTP
smart host.
It seems like the MX record is still pointing to the Internal Exchange Server which leads to routing all mails sent to Exchange Online users to go through the local one. When MX record is pointing directly to Exchange Online – there will be just a few SMTP traffic and it will be Inbound. (as most of the users are already Online)
