How to configure a CodeTwo domain in Office 365

Problem:

After you registered your Office 365 tenant in CodeTwo Admin Panel, a new accepted domain was added to your Office 365 tenant:

[your unique ID].smtp.codetwo.online

When you view this domain in your Microsoft 365 admin center (Office 365 admin center), the domain may have an alarming status like No services selected, Not connected to services, Incomplete setup (Fig. 1.) or similar, depending on your region and tenant settings. Also, Office 365 may send you various notifications or display warnings related to this new domain.

Solution:

This new domain is used to relay your messages and improve your email security (our software uses TLS certificate-based connectors). After the domain is created, it has the No services selected or similar status, which might sound alarming. You can ignore this status and related Microsoft 365 notifications because CodeTwo Email Signatures for Office 365 is configured and working correctly. Your mail flow and email signatures are not affected by this status. Such status remains because the API used by our software does not allow us to change it in your tenant. This is further confirmed in the status disclaimer (Fig. 2.).
