Hi R.H.Weber,
As I understand it, after changed the public-facing website from default website address to your custom website address. Currently, the public-facing website works fine with the custom website address. But in Microsoft Online Portal (MOP)>Domains, it still shows the default website address.
Please correct me on time if I misunderstand the issue.
If so, I want to confirm that if users click Member Login in your public website, the URL begins with your custom website address or default website address?
Moreover, if you don’t use the default website address again, this may not affect your public-facing website.
Thanks,
Eric Sun
