Hello,
I'm trying to register my domain on new tenant but i received this message : We've confirmed that you own itnetxxxxx.eu, but we can't add it to your account because the domain is already added to another Microsoft 365 organisation: M365x366821.onmicrosoft.com.
Log in to the administration centre as administrator for this organisation and delete the itnetxxxxx.eu domain. Try resetting the administrator password if you can't log in. You should be able to add the itnetxxxx.eu domain here after completing this step.
If you are unable to access M365x366821.onmicrosoft.com, please contact our support team for assistance.
I'm trying to delete the domain on old tenant but it seems to be desactivated : Sign-in failed
Error code: AADSTS5000224

Based on your description, it looks like you're encountering error code AADSTS5000224 while accessing the Azure Portal. This error typically occurs when authentication for your Azure tenant has been temporarily disabled due to a recent security incident. To resolve this, we need to re-enable authentication for your tenant.
As you shared the tenant details via email, I have involved the Product Group team to remove the authentication block.
Once the block is removed, I'll provide you with an update here.
