The domain portion of the userPrincipalName property is invalid. You must use one of the verified domain names in your organization.
My login feature is independent of domain, so how can this be resolved?

Verify publisher domain for AAD multi-tenant app on tenant migration

We're moving an existing application registration from our corporate tenant (foo-corporate.com) to a new dedicated tenant (bar-app.com).
The process of moving the app registration requires to create a new app registration in the bar-app.com tenant.
According to this article, we need to verify the publisher domain (foo-corporate.com) in the new dedicated tenant (bar-app.com).
This is necessary, as the user will otherwise see unverified as the publisher on the consent screen (see #5 on screenshot) instead of the publisher (foo-corporate).
The process to verify the publisher involves hosting a microsoft-identity-association.json on https://foo-corporate.com/.well-known/ to verify the publisher.
Questions
Is there another way to verify the publisher foo-corporate.com for the new app registration in bar-app.com tenant? We're a large enterprise and our development team doesn't have access to the hosting of foo-corporate.com (public website), so we can't put the json file there. I assume this is the case for most larger enterprises.
In case there is no other option, do we need to host this file permanently or is it only needed for a first verification and can be removed afterward?
Update 1
The question is about publisher domain verification and not custom domain verification as the first answer to this questions assumed.
Sample Consent Screen
You can verify your domain in Azure AD by adding a custom domain. You can verify it using any of the methods here, which include creating DNS records or placing a file on the site. The file is only required while verifying the domain; It can be deleted after the status shows as verified.
Azure Portal -> Azure AD -> Custom Domains:
From this page:
New applications
When you register a new app, the publisher domain of your app may be
set to a default value. The value depends on where the app is
registered, particularly whether the app is registered in a tenant and
whether the tenant has tenant verified domains.
If there are tenant-verified domains, the app’s publisher domain will
default to the primary verified domain of the tenant. If there are no
tenant verified domains (which is the case when the application is not
registered in a tenant), the app’s publisher domain will be set to
null.
Adding a tenant verified domain gives you more verification options. Verification ensures non-repudiation which is essential for Microsoft to display an application's publisher to an end user.
Without placing a file on a website for the domain (I don't have a website), these are the options available to me:
The first is the domain I verified through DNS, the second is the onmicrosoft.com default domain. Using the onmicrosoft domain however will not suffice as it is an Available domain as opposed to a Verified one.

Azure -- Ignoring domain when logging in?

I'm using Azure's SSO service, and every time a user wants to login in to their Office 365 portal, they have to enter their whole username and their domain?
Is it possible to create a website so that Azure knows what domain we are so the users don't have to type in their domain? This is an issue for us because their actual email and Active Directory usernames are two different things.
You van specify a domain hint, which sends users to the correct azure login page: https://blogs.technet.microsoft.com/enterprisemobility/2015/02/11/using-azure-ad-to-land-users-on-their-custom-login-page-from-within-your-app/

Unable to verify this domain because it is used elsewhere in Office 365

To whom it may concern.
We run ADFS with local AD syncing to Azure AD for SSO with Azure and Office 365.
We recently moved our Azure subscription to a new account. We were instructed to add the AD for the domain again. There is a persisting issue that we cannot verify the domain. Due to this issue we cannot access certain sites/services with delegated accounts, i.e. only the microsoft account that is the owner can access the services.
The error when trying to verify the domain with Confirm-MsolDomain -DomainName cognadev.com is
"Unable to verify this domain because it is used elsewhere in Office
365. Remove the verified domain from the other service before adding it here."
How can I see where else the domain is used?
How can I remove the domain from where it is used, without losing mailboxes etc?
Please advise.
We had to do two things to get everything working again:
We removed all the user accounts and groups from the Azure AD for the account. This allowed the custom domain to be deleted from the old account and then we were able to verify the domain on the new account.
We migrated all users to new mailboxes and imported their old email from .pst files.
Quite a mission.
Lesson learned.
