Re: Domain setup and problem

Hi Talweb,

I’d like to confirm if you want to delete the domain name added in your Office 365 account?
If yes, please remove the domain from all user, email, or Office 365 accounts associated with the domain, such as proxy addresses, Distribution groups and so on.

Here are the articles for your reference, you can refer to “Remove a domain " part in the following articles:
