We have two domain sites on sharepoint.

I would like to create another sharepoint site, but I want to use the other domain that we have created.
How would I do that? Cause when I just create a site it doesn't let me choose what domain to use.

Microsoft 365 and Office | SharePoint | For business | Windows

    Hi @Cams ,
    Thanks for your detailed explanation.
    The green domain you created is an onmicrosoft.com fallback domain in Microsoft 365.
    It serves as a default email routing address for your Microsoft 365 environment. When a user is set up with a mailbox, email is routed to the fallback domain. Even if a custom domain is used (for example, tailspintoys.com), if that custom domain is deleted from your Microsoft 365 environment, the fallback domain ensures that your user's email is successfully routed.

    A sharepoint tenant can only have one Top-level SharePoint site. You cannot create sites using another domain.
