The message "You've tried to sign in too many times with an incorrect account or password" appears when Microsoft detects too many failed sign-in attempts or otherwise risky sign-in activity, even if the credentials being entered are actually correct. This is a protection mechanism and can temporarily block sign-in from a specific device, app, or network.
From similar reported cases, there are a few concrete paths that have resolved this situation:
- Stop retrying for a while
Multiple rapid attempts can extend or retrigger the block. Guidance from support is to:- Completely stop trying to sign in for at least 24 hours.
- Do not keep testing the password during that period, as repeated attempts can reset the time lock.
- If the issue persists after 24 hours, extend the waiting period up to a week.
- Try another sign-in method (if available)
On the password page, if there is an option like “Other ways to sign in” or “Use another way to sign in”, use it.
Possible alternatives (if already configured on the account) include:- Approve sign-in with a mobile app (such as Microsoft Authenticator).
- Use a security key, PIN, or Windows Hello.
- Send a code to a registered email or phone number.
If one of these works, then change the sign-in preference for the account to rely on that method going forward.
- Switch device or network
Blocks can be tied to a specific device or network:- Try signing in from a different device (another PC, phone, or tablet).
- Try a different network (switch between Wi‑Fi and mobile data, or use another Wi‑Fi).
This is explicitly recommended for both Error 400 and verification-code blocks and applies similarly here.
- Use the official sign-in helpers and troubleshooters
Microsoft provides automated flows that can detect and guide through sign-in blocks:- Sign-in Helper tool for general Microsoft account sign-in issues: this is the primary entry point when sign-in fails repeatedly.
- For Outlook.com/Hotmail specifically, use the sign-in troubleshooter or account troubleshooter linked from the Outlook.com help pages.
These tools can surface options like account recovery, unblock flows, or verification challenges.
- If the account is blocked or at risk
When repeated attempts and unusual activity are detected, the account or a specific verification method can be blocked. In that case:- Follow the guidance under “How to fix ‘Try another verification method’ error message”:
- Try a different verification method already on the account (alternate email instead of SMS, for example).
- Try another network.
- Wait (24 hours to up to a week) without repeated attempts.
- If still blocked after that, use the account recovery and account reinstatement flows referenced in the Microsoft account help pages.
- Follow the guidance under “How to fix ‘Try another verification method’ error message”:
- If the problem is only on one device (for example, iPhone)
Similar cases show that the account can work on one device (PC) but be blocked or stuck on another (phone). Resolutions reported include:- Successfully resetting the password from the affected device and then signing in again. Once the password was reset on the phone itself, sign-in to live.com and then adding Outlook back to the Mail app worked.
- Adding another sign-in method (for example, Microsoft Authenticator) on the Microsoft account via a working device, then using that method to add the account back on the phone.
If none of the above resolves the issue after the recommended waiting period and use of the helper tools, the next step is to continue with the Microsoft account recovery and reinstatement processes referenced in the account help pages, as that is how blocked or suspicious accounts are formally reviewed and unblocked.
