Prefill Username for Authentication
You should be able to pass the email value as login_hint. I.e.:
https://login.microsoftonline.com/common/oauth2/authorize?login_hint=email address removed for privacy reasons&blabla_other_params_blabla
Do make sure to add the remaining parameters as needed, you will need at least the client_id and redirect_uri if hitting the login page directly. Most first-party services support login_hint as well, so you can bypass all that, for example for Outlook you can use:
http://outlook.office.com/?login_hint=email address removed for privacy reasons
