Hi PS827
From your post, I understand how frustrating this is, especially when it affects both email addresses and you’re seeing different sign-in prompts across devices.
Have you already tried the Q&A Assist suggestions yet? If yes, what happened?
To narrow this down, could you also confirm these:
- Are you currently able to sign in successfully on the web at https://outlook.live.com, even if apps prompt for extra verification?
- When you see messages like “login too many times” or requests for a passkey / PIN, does Microsoft ask you to wait before trying again?
- In case the sign‑in is blocked, are you being asked to add a passkey, enter a PIN, or use a code sent to a device you no longer have access to?
In the meantime, please stop all sign‑in attempts for at least 24 hours from all devices and browsers, then try signing in again on Outlook.com website first. Attempting sign‑in too frequently can extend the temporary block.
For more details, you can see these official guides:
Looking forward to your reply so I can assist further. I truly appreciate your patience and understanding.
