Hi JIM MY,
Welcome to the Microsoft Q&A forum.
I understand how frustrating this situation can be, especially when you keep seeing messages about too many sign‑in attempts and are still unable to access the account even after changing the password.
I see there is already a Q&A Assist response above, and the main explanation there is generally correct. Repeated sign‑in attempts can trigger a temporary security restriction on Outlook.com/Hotmail accounts, and changing the password alone does not immediately remove that block. May I check whether you have had a chance to review or try the steps suggested in that answer?
To add some additional context, when this type of message appears, it usually means the account has entered a temporary protection state. During this period, continuing to retry sign‑ins or resetting the password multiple times can extend the restriction, which is why the issue may persist even after you have logged out or updated your credentials. In most cases, the system requires a cooling‑off period before normal sign‑in attempts are accepted again.
One more thing to keep in mind is that other devices or mail apps signed in with this account can keep attempting to connect in the background. If possible, it may help to temporarily pause mail sync or remove the account from those apps until access is restored, so the protection window is not unintentionally extended.
If your concern is whether the account is secure, reviewing the Microsoft account recent sign‑in activity after access is restored can help confirm whether the block was triggered by repeated attempts or unusual activity (What is the Recent activity page? - Microsoft Support). You can also refer to the official guidance for unblocking an Outlook.com account, which routes through the Sign-in Helper flow (Unblock my Outlook.com account - Microsoft Support). This is part of automated account protection and cannot be manually bypassed from the forum.
I hope this helps clarify why the sign‑in issue can continue after a password change, and please let me know whether you were able to try the steps already provided so I can share more targeted information if needed.
