How to configure a CodeTwo domain in Microsoft 365


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

[your unique ID]

When you view this domain in your Microsoft 365 admin center, the domain may have an alarming status like No services selectedNot connected to servicesIncomplete setup (Fig. 1.) or similar, depending on your region and tenant settings. Also, Microsoft 365 may send you various notifications or display warnings related to this new domain.

The CodeTwo domain is necessary for CodeTwo Email Signatures 365 to work correctly. Do not remove it from Microsoft 365. If you did, contact us.


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 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.).
