Check Microsoft’s Service Health Status first because Hotmail stopped working suddenly on both the PC and smartphone; if Outlook.com is not green, wait for Microsoft to restore the service before changing the password or app settings.^1^
Open the Microsoft Service Health Status site on either device.
- Outlook.com shows an incident: No account repair is required. Wait until its status returns to normal, then try again on the PC and phone.
- All services are healthy: Continue with the account-specific checks below.
Microsoft’s Outlook.com issues page also lists recent known problems and available workarounds.^1^
2. Test the account through the official website
On the PC:
- Open a private or InPrivate browser window.
- Go to the official Hotmail/Outlook sign-in page: outlook.live.com.
- Enter the complete Hotmail address, including the correct domain—for example,
@hotmail.com rather than a different country domain.
- Enter the Microsoft account password. Hotmail uses the same password as the associated Microsoft account.^2^
If this works, the account itself is accessible. Sign out of the Outlook mobile app, reopen it, and sign in with the same full address and password.
3. If the website also rejects the sign-in
Run Microsoft’s Sign-in Helper. Enter the Hotmail address or associated phone number and follow the result shown. The tool checks for account-specific problems and provides the corresponding recovery action.^3^
Use the matching path:
- Password stopped working: Complete the identity-verification process and create a new password. Check the exact email spelling and domain first; if the address is not recognized, try another alias or phone number associated with the account.^4^
- Account blocked: Follow the unblock procedure offered by the helper. Microsoft can temporarily block an account after detecting unusual sign-in activity.^2^
- Verification code problem: Select the verification-code troubleshooting option offered by the Sign-in Helper.
- “Account doesn’t exist” or username not recognized: Use the Sign-in Helper rather than repeatedly attempting passwords.^3^
After access is restored on the website, sign back into the smartphone app. If a password was changed, enter the new password when the app requests updated credentials.
