Configuring Microsoft 365 as a Destination Server

You can forward emails processed by our services to your Microsoft 365 environment. To do this, set up Microsoft 365 as the destination server in the Control Panel.

You have activated Spam and Malware Protection for the corresponding domain.

By setting Microsoft 365 as the destination server for incoming emails, emails can be forwarded to your mailboxes at Microsoft 365 after being processed by 365 Total Protection.


The address of the destination server for forwarding emails is determined automatically during the initial synchronization. This setting is only necessary if the address of your server at Microsoft 365 has changed.

  1. Log in to the Control Panel with your administrative credentials.
  2. From the scope selection, select the domain for which you would like to configure Microsoft 365 as a destination server.
  3. Navigate to Security Settings > Spam and Malware Protection.
  4. Select the tab General Settings.
  5. Select the domain in the drop-down menu under Domain.

  6. Select the option IP/Hostname under Primary Environment Settings > Destination.
    An input field for IP addresses or hostnames is displayed.
  7. Enter the destination address of your Microsoft 365 environment under Destination server.

    You can find the destination address in your Microsoft 365 environment in the Microsoft 365 portal at Admin Centers > Setup > Domains, section Exchange Online > MX.
