What to do if I removed the CodeTwo domain assigned to my Microsoft 365 tenant?
You removed the CodeTwo domain that was added to your Microsoft 365 (Office 365) tenant during the provisioning of CodeTwo Email Signatures 365.
After you add a tenant to CodeTwo Admin Panel and the provisioning of our services is finished (learn more), a new CodeTwo domain appears in your Microsoft 365 (Fig. 1.). This domain is unique for a given tenant and must be created, so that CodeTwo connectors can work properly in your Microsoft 365 organization. See this Microsoft article to learn more about certificate-based connector configuration.
If you remove this new domain, the CodeTwo connectors (and, as a consequence, the CodeTwo services associated with your tenant) might stop working.
If you remove the CodeTwo domain, your mail flow might be blocked. This may not happen right away - it depends on how fast this change (the removal of the CodeTwo domain) propagates in your Microsoft 365. Still, we advise that you react quickly.
To solve this issue, you need to follow these steps:
- Sign in to the Exchange admin center (EAC), go to Mail flow > Rules. Write down or take screenshots of your CodeTwo transport rule (see Fig. 2.). This will later help you recreate the scope of users whose emails are routed through CodeTwo and apply your custom settings (e.g. conditions and exceptions) to the rule.
