Cannot access Hotmail: login skips password and shows 401 error

Question

Subject: Outlook login fails with 401 error after password reset

Dear Microsoft Support,

I am unable to access my Hotmail email account from any browser (Chrome, Edge, Incognito) or from my mobile phone. After a recent password change, the login process skips the password field and automatically redirects me to a broken session.

I always get a 401 Unauthorized error at this URL:
https://outlook.live.com/mail/0/?bO=1&msalAuthRedirect=true&sessionId=a4610615-b08a-4c89-a42c-93fa1df7bb7c

I have already:

• Changed my password
• Signed out of all devices
• Cleared all browser cookies and data
• Used different browsers and devices
• Removed conflicting recovery data (shared phone number with another Microsoft alias account)

My Microsoft account works correctly at account.microsoft.com, but Outlook Webmail always returns a 401 error and does not allow me to enter my password manually.

I suspect there is a corrupted authentication token or identity conflict between my Hotmail account and a second alias identity previously configured on my mobile device.

Please check and reset my session/token data on the server side or let me know how to proceed.

Thank you very much for your assistance.

Best regards,
Romina Fucà
