We're working on getting OOB authentication set up to authenticate using Azure AD. When we use urn:ietf:wg:oauth:2.0:oob (but not a normal URL), it allows us to enter the email, but then hangs with the wait dots going across the top. It never arrives at where you can enter the password.
I enable debug mode, and have the following IDs:
Request Id: 0c5a4000-24f7-4286-9aa0-8492e504ef00
Correlation Id: e9dc363f-2537-42e3-84e9-df8490374c30
The URL I start at is (Client ID redacted): https://login.microsoftonline.com/common/oauth2/v2.0/authorize?client_id=&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&response_type=code&scope=Mail.Send+User.Read&state=state
