I believe the correct answer is not listed as an option. The correct answer would be sub1.contoso221018.onmicrosoft.com and contoso221018.onmicrosoft.com.

Domains with status "incomplete setup" can not be used

I've created accounts with domains that were in the incomplete setup status and domains with service issues, so I believe it is D.

You can assign all of them, but can't use it.

Contoso.com can be used also (anyone suggesting B is the answer, one of the options for B is a sub domain of Contoso.com and has the same status so that cant be right!). I believe the answer to be D (All of them) - tested in a lab and Incomplete Status sub domain still allowed me to assign the domain to a user. Answer is D.

contoso221018.onmicrosoft.com, Sub1.contoso221018.onmicrosoft.com, and Sub2.contoso221018.onmicrosoft.com . Because contoso221018.onmicrosoft.com has already been verified, sub1 and sub2 are sub-domains of contoso221018.onmicrosoft.com, all three domains are able to use.

Hello guys, the correct answer is D. I tested 4 domains with the three status and the three of them are functioning without errors.

The Answer is B, Do you guys see Sub.contoso221018.onmicrosoft.com this domain listed in the domain list. It is only Sub1 and Sub2 only. C. only contoso221018.onmicrosoft.com, Sub.contoso221018.onmicrosoft.com, and Sub2.contoso221018.onmicrosoft.com

Hello Guys, Incomplete domains cannot be used to create users. otherwise, a domain with a service heath issue is already verified an can be used when creating a user I Test it. Regards.

Microsoft Azure / M365 Domain name: 1) Sub1.contoso221018.onmicrosoft.com | Status Possible service issues 2) contoso.com | Incomplete setup 3) contoso221018.onmicrosoft.com | Healthy 4) Sub2.contoso221018.onmicrosoft.com | Incomplete setup Which domain name suffixes can you use when you create users? Only response choice ChatGPT: You can use the following domain name suffix when you create users: contoso221018.onmicrosoft.com Why not Sub1.contoso221018.onmicrosoft.com too? ChatGPT: I apologize for any confusion. You can indeed use "Sub1.contoso221018.onmicrosoft.com" as a domain name suffix when creating users, as long as it's available and there are no service issues. So, the correct response would be: Sub1.contoso221018.onmicrosoft.com contoso221018.onmicrosoft.com

You can still create a user with an incomplete setup domain

If you go by the picture, the answer is B. This is because contoso.com and sub2.contoso221018.onmicrosoft.com have an incomplete setup. If you go by the logic, it's a complete nonsense since sub2 has already been verified via the main domain.

After reading through everyone's responses I was so confused I setup the question in my 365 lab environment. I was able to use a healthy domain, and its subdomain with incomplete setup, and its 2nd subdomain with Possible service issues to create a new user. I could not use an unverified root domain. So the correct answer (lab tested 4/7/24 is C.

contoso.com and sub2.contoso221018.onmicrosoft.com domains are in incomplete setup status. As such, you cannot use the domains yet; you cannot create users that contain the contoso.com and sub2.contoso221018.onmicrosoft.com domains. https://learn.microsoft.com/microsoft-365/admin/setup/add-domain?view=o365-worldwide

Isn't it a bit confusing? You can assign alle Domains to a User, but you can't use it to receive mails for example.

Healthy & possible service issues CAN be used for the following reason: If a domain is either healthy or stating errors, it means the domain has been submitted as a custom domain and VERIFIED (THIS IS THE IMPORTANT PART). Incomplete setup means the domain has not been verified which means it cannot be used.

Please ignore my comment I got wrong and B is correct
