Databias provides a routing option to enable our customers on the Microsoft 365 platform to route their already branded mail (which has traveled out from 365 to Databias via their configured rule and connector) back to 365 for final delivery to recipients.
When using Google Workspace or Office 365 excluding senders from branding with Databias is quite simple. Either login to the Google Workspace Admin or Exchange admin site and modify either the rule (which points to a connector) for Office 365 or the Google Workspace Gmail Admin as per the below screenshots.
To setup routing on Microsoft 365 for email branding, you need to setup a connector and a rule in the Exchange Admin Centre and then apply it. This document takes you through the steps to do this on the management platform, first adding the connector and then the rule.
