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 Office 365 admin center, it has the Setup in progress status (Fig. 1.). Also, Office 365 may send you various notifications or display warnings related to this new domain.

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