Title: Messenger: sign in automatically with the user’s Microsoft (Entra ID) account

Messenger only offers email sign-in with a one-time code. On Entra-joined laptops, Windows already knows who the user is, so asking them for an email address and a code adds friction to the moment they need help.

Please let Messenger sign users in automatically with their Microsoft work account. On an Entra-joined device it could use the signed-in Windows account silently (Windows single sign-on), and fall back to a “Sign in with Microsoft” button. Matching the user’s Entra UPN to the Gorelo contact would also tie each ticket to the right contact and device without the user typing anything.

Microsoft’s outage today shows why this matters. Email codes depend on the user’s mailbox receiving the message, and a user whose email is down is exactly the person who needs to reach us. Keep the email code as a fallback, but don’t make it the only way in.

This fits naturally with the native Microsoft 365 integration you’re building. Once a client’s tenant is connected by admin consent, Gorelo already knows each user, their UPN and their client, so Messenger sign-in could build on that consent.
