Using Outlook for Android for personal email and calendar management
Welcome Lenny Fridman,
Thank you for providing the detailed troubleshooting history. Since the account works normally in Outlook.com, Outlook for Windows, and Samsung Email, and the same behavior occurs on multiple Android devices, let's check a few account-specific settings that may affect the Outlook Mobile sign-in flow.
Could you please confirm:
- Is this Hotmail account using password-only sign-in, or have you enabled two-step verification on the Microsoft account?
- Can you successfully sign in to the account from an Android browser using an InPrivate/Incognito window at https://outlook.live.com?
- Under Microsoft Account > Security > Advanced security options, do you see any unusual sign-in restrictions, security alerts, or recent security changes on the account?
As a quick test, please also try:
- Open a browser on the Android device and sign in to the Hotmail account at https://outlook.live.com.
- Leave the browser signed in.
- Open Outlook for Android and try adding the account again.
