Enabled "using email as alternate login ID". Was happy to see we can use a proxyAddress to login, but unhappy to see i can't use it to login to a Azure AD joined PC.
I'm able to register the laptop, but after that i can't login :(

Thanks for the links.
I've read all the articles, but it isn't working.
Logging in with the UPN works without problems, but logging in with the alternate ID doesn't work.
In this article (https://learn.microsoft.com/en-us/azure/active-directory/authentication/howto-authentication-use-email-signin) is being mentioned
"Currently, this feature is not supported on Azure AD joined Windows 10 devices for tenants with cloud authentication. This feature is not applicable to Hybrid Azure AD joined devices."
So i'm afraid it won't work at all.
Anyone knows the ETA of the full release?
