Setting up and managing device configurations using Intune
Hello Csongor Portik-Lukács,
Just to clarify - AllowedAccountUPNs helps limit sign‑in to approved org accounts, but it doesn’t handle automatic sign‑in or user detection. The first sign‑in (into any M365 app) still needs to be done by the user. Following apps signing in might pick up the user already logged in.
Docs here for reference: https://dotnet.territoriali.olinfo.it/en-us/intune/intune-service/apps/app-configuration-policies-use-android#allow-only-configured-organization-accounts-in-apps
Hope this helps!
