I cannot log in to my Microsoft apps on my phone.

Follow these steps in order, based on the error about too many attempts and using Outlook on a phone:

1. Wait out the lock and avoid repeated attempts
   • The message about trying too many times or too many codes indicates a temporary block due to unusual activity or high volume of requests.
   • Do not keep retrying, as repeated attempts can extend the block. Wait at least 24 hours; if still blocked, wait up to a week before trying again.
2. Use the Microsoft sign-in helper to diagnose the issue
   • From a browser (on a computer or your phone), go to the Microsoft account sign-in helper and follow the prompts: Sign-in Helper.
   • Enter the email or phone number used for the account. The tool will detect common sign-in problems and tell what to do next.
3. If the account might be locked
   • If the account itself has been locked due to suspicious activity, go to https://account.microsoft.com and sign in to request a security code: Sign in.
   • Use any phone number that can receive SMS (it does not have to be already on the account) to get the code.
   • After entering the code, be prepared to set a new, strong password.
4. Reset the password if the password is not accepted
   • If the password is correct but not accepted, use account recovery:
     • Go to Recover your account.
     • Enter the email/phone/Skype name, choose where to receive a security code, enter the code, then set a new password.
   • If the username is not recognized, try any other alias or phone number on the account and verify the domain (for example, outlook.com vs outlook.co.uk).
5. Fix verification-code and “try another method” issues
   • If seeing messages like “try another verification method” or codes not arriving:
     • Try a different verification method on the account (alternate email instead of SMS, or vice versa).
     • Try a different network (switch between Wi‑Fi and mobile data, or use another Wi‑Fi).
     • Do not send many repeated code requests; wait 24 hours before trying again if blocked.
6. Get Outlook working again on the phone
   • After the account is unlocked and the password is reset successfully in a browser, test sign-in at https://account.microsoft.com or Outlook on the web.
   • On the phone:
     • Make sure the Outlook mobile app is up to date: download the latest version.
     • Remove the existing account from Outlook/mobile mail app.
     • Add the account again using the new password.
7. If still unable to sign in after recovery
   • Use the sign-in helper again to see if it reports that the account does not exist or remains locked and follow its guidance.
   • If the helper cannot resolve it, use any working Microsoft account (or create a new one) to contact Microsoft Support as described in the Q&A guidance, and explain that the personal account is locked and verification codes are blocked.
