Cant configure Outlook for a domain error message “There’s a temporary problem with the service. Please try again. If you continue to get this message, try again later”

No matter what I do. I tried to fill in all the profile information, but even when I click on some of the tabs it sends me to the page to send an email to verify my identity.. When I click the link in the mailbox, I get the same message again. How do I fix this, because it seems permanent and not temporary! How can I successfully verify the domain I registered into outlook since the link sent by mail keeps sending me to the error page? I have several domains I want to handle through Outlook and all of them have the same recurring issue.
