Outlook email problem logging in. I get a message from Yahoo requiring me to log in but can't log in. I have been using Outlook Email for years and occasionally Yahoo captures my account and requires me to log in to Yahoo. I have logged in and get a message "Its not you it is us"

    Hi!

    Third-party providers usually require you to use an App Password instead of your regular password. The app password is generated on the provider's website (in your case, Yahoo). Have you already done this and tried using the app password?

    Please answer all the questions below:

    Can you access your email normally via Webmail (the Yahoo website)?

    Do you have access to your email on another computer or mobile phone?

    Have you tested it using the New Outlook?Test it in the New Outlook app for Windows:

    For a Yahoo account in classic Outlook, the most common causes are stale saved credentials in Outlook, an outdated password in Outlook after a Yahoo-side change, or Yahoo requiring Outlook to sign in again.

    Try these steps in order:

    1. Check whether Outlook is repeatedly using old Yahoo credentials
      • Close Outlook.
      • Open Credential Manager from the Windows Start menu. On some systems, open Control Panel first, then Credential Manager.
      • Go to Manage your credentials > Windows Credentials.
      • Under Generic credentials, find entries starting with MicrosoftOffice16_Data:OAUTH2.
      • Remove the entries for the Yahoo account.
      • Restart Outlook and sign in to the Yahoo account when prompted.
      • If Outlook still does not sync immediately, restart Outlook again.
      This is intended to force Outlook to prompt for sign-in again without removing the account.
    2. If the Yahoo password was changed recently
      • After a password change, Outlook may keep using an old token for up to one hour before prompting again.
      • If waiting is not preferred, use the Credential Manager steps above to force the sign-in prompt.
    3. Verify the password stored in Outlook
      • If the password was changed with Yahoo, it must be changed on Yahoo first.
      • Then update the password in Outlook.
      • In Windows, open Control Panel > Mail > Email Accounts.
      • Select the Yahoo account and choose Change.
      • Under Logon Information, verify the User Name is the full Yahoo email address and the password is correct.
    4. If Outlook never asks for the Yahoo password during setup or repair
      • In Control Panel > Mail > Email Accounts > New or when editing the account, make sure Require logon using Secure Password Authentication (SPA) is unchecked.
    5. If Yahoo still fails with “It’s not you, it’s us”
      • That message is on the Yahoo side. For non-Microsoft accounts such as Yahoo, sign-in issues with the provider must be resolved with that provider.
      • In the meantime, if access in Outlook.com is the goal, mail from the Yahoo account can be forwarded to an existing Outlook.com account.

    Warning: if using the optional registry workaround for stuck Yahoo identity data, registry changes are risky and can affect Outlook sign-in behavior if the wrong key is deleted. Use the Credential Manager method first.
