Because sign-in works on the Outlook app but not on computers, the account itself is still valid, but Microsoft’s protection systems are likely blocking some sign-in methods due to unusual activity or too many attempts.
Use these steps in order:
- Stop repeated attempts for a while
- Too many password or code attempts can trigger a temporary block.
- Do not keep retrying on the same device or method; this can extend the lockout.
- Wait at least 24 hours before more attempts, and up to a week if the problem persists, as recommended for blocks.
- Try a different verification method
- When prompted to verify, choose the alternate email option instead of SMS if SMS is failing.
- If one method (like text to cell phone) is giving errors, Microsoft recommends switching to another verification method already on the account (for example, alternate email) to receive the code.
- Try a different network or device for the browser sign-in
- Sign in from a different network (for example, home vs. work, or switch between Wi‑Fi and mobile hotspot) when using a computer browser.
- Go to the standard sign-in page for Outlook.com (Hotmail is now Outlook.com) and sign in with the same Microsoft account username and password used on the phone.
- Use the official sign-in troubleshooter
- For Outlook.com/Hotmail accounts, use the sign-in troubleshooter to diagnose and fix sign-in problems: use the “Start troubleshooter” link from the Hotmail sign-in help article.
- For general Microsoft account sign-in issues (including blocks and verification problems), use the sign-in helper: it will check the account and show specific steps based on what it finds.
- If you see messages about blocks or “try another verification method”
- Blocks can be caused by:
- Unusual activity or sign-in patterns.
- High volume of verification requests.
- Suspicious traffic from your location.
- To resolve:
- Use another verification method already on the account (for example, alternate email instead of SMS).
- Switch to another network and try again.
- Avoid repeated attempts; wait 24 hours or longer before trying again.
- Use the sign-in helper link provided in the block guidance to see available recovery options.
- If still stuck and no method works
- Use the Microsoft account sign-in helper or Outlook.com sign-in troubleshooter from a computer browser and follow all prompts.
- If the tools do not detect a problem or you still cannot sign in on a computer after waiting and trying alternate methods, use the support options offered at the end of those tools (such as guided self-help or escalation paths) as available in your region.
Once access on a computer is restored, review the account’s security info and consider enabling or updating passwordless methods (such as Microsoft Authenticator) to reduce reliance on SMS codes, which can be less reliable.
