I have just enabled Modern Authentication for my Exchange Online environment. I also have Microsoft Authenticator passwordless sign-in enabled for my Exchange Online environment. With both of those things enabled, my questions are:
1. How long does it normally take for Modern Authentication to become enabled, once I activate it?
2. What else do I need to do in order to enable the Microsoft Authenticator Passwordless Sign in for both my login to Windows 10 Business profile, when using an Azure AD Joined account?
3. What else is needed to be done to have Microsoft Authenticator Passwordless Sign In activated when launching Outlook 365 (latest) on Windows 10 Business?
4. How can I see what protocol my Outlook 365 client is using to connect to my Exchange Online mailbox?
