Changing domain in Office 365 doesn't sync in Azure Portal
My organization has both office365 and Azure Portal. I am the sole administrator for both. We have been using our onmicrosoft.com addresses and just signed up for a new domain through Microsoft. After I switch my domain from the onmicrosoft.com to the new one, I can easily login to the Office365 admin portal with the new domain. But I can't login to Azure -- it doesn't recognize the new domain at all. However, if I change my domain back in office365 to the onmicrosoft.com one, than I can use the onmicrosoft.com login to log into Azure. Changing the domain in Office365 is almost instantly recognized in Active Directory.
How can I fix this?
